- A short description of each screen saver.
- -----------------------------------------
-
- Fractal Worlds I
- ----------------
- This uses some of the ideas behind the mathematical theory of fractal
- sets in order to generate an amazing variety of beautiful patterns;
- sometimes a bit chaotic sometimes more organised.
- (On installation try the "Test" button several times to see the wide
- variety of different forms.)
-
- Fractal Worlds II
- -----------------
- Somewhat similar to Fractal Worlds I, but with a wide range of different
- visual effects.
-
- Grow Shapes I & II
- ------------------
- These have a wide variety of setup options for you to customise
- to your own wishes. See the section below for more information on
- Grow Shapes I and II.
-
- Hexxes
- ------
- Hexagons move across the screen just missing each other. (Do they
- rotate?) They leave behind them colour trails producing a continuously
- changing pattern on the screen.
-
- Mandelbrot
- ----------
- Another example of amazing images produced by applying the mathematics
- of fractals, but very different from "Fractal Worlds". First the full
- fractal is shown then the image is dissolved and then a smaller part
- is shown on a larger scale. This process is repeated focusing in a
- randomly selected point in the border area of the fractal; showing detail
- within detail, form repeated within form, the whole repeated within a
- part.
-
- Mondrian
- --------
- An attempt to simulate the painter in his mature style. (Are the
- generated pictures as good, or even better than the real thing?)
-
- Runel
- -----
- The "Runel" moves and twists across the screen painting and
- re-painting in various modes, producing a wide range of pattern and
- colour effects.
-
- --------------<>--------------
-
- Installation
- ------------
- Step 1
- Copy the eight *.SCR files from the diskette (or from the collection
- of unpacked files) to the WINDOWS directory on your hard disk.
- INSTALL.BAT can be used to perform this step.
-
- Step 2
- Select the Control Panel icon from Main and then the Desktop icon.
- Scroll down the list of screen savers and select the screen saver
- you wish to have a look at and possibly keep installed.
- Selection of a screen saver may differ with Windows 95; please
- refer to the Windows 95 User's Guide.
-
- ------<>------
-
- Operation with Windows
- ----------------------
- These screen savers are a 16 bit programs written originally to work
- with Windows 3.1 and 3.11. They are designed to be Windows 95 compatible.
- Note that Windows screen savers can only operate while Windows is being
- run.
-
- If you have any problems with these screen savers, or notice any
- change in the way they operate under Windows 95, or have any other
- problems with our software or want to discuss anything concerning my
- software please dont hesitate to contact me, (preferably by email).

- Notes on Grow Shapes
- ====================
-
- Versions
- --------
- Two versions of Grow Shapes are supplied. Version II has a more
- elaborate sequence of screen images but uses less computer memory
- to build the screen picture.
-
-
- Brief general description of Grow Shapes
- ----------------------------------------
- Shapes of different types 'grow' at random positions on the screen.
- Once at their full size they gradually fade into the background. Up to
- about sixty shapes can exist on the screen at the same time.
-
-
- Configuration options
- ---------------------
- Grow Shapes has a wide range of configuration options. Choosing
- different options can give a distinctly different look to the picture.
- As with other screen savers, the current configuration attributes are
- saved in the CONTROL.INI file.
-
- List of options -
-
- Shape.
- There are eight different types of shape. One or more can be selected.
- A shape is selected by checking the shape's check box and placing a
- non-zero value in the "proportion" box.
- Although all eight shapes can be selected together, the best
- combinations do not necessarily include all the shapes.
- Note that for a shape to be selected the check box must be checked as
- well as a non-zero value being entered in the "proportion" box.
-
- Proportion.
- A value between 1 and 999. This gives the relative number of times
- shapes of this type will appear.
-
- Maximum and minimum size.
- In units of 1 to 100. For each individual shape created, a size is
- randomly selected between the specified minimum and maximum values.
- For rectangles and ellipses, size refers to the longest dimension
- which will be randomly the height or width.
- By setting the maximum size equal to the minimum size, the size of
- squares, circles, hexagons, and stars can be set to a precise constant
- value.
-
- Star shape.
- The star is always eight pointed, but the bluntness and sharpness of
- the points can be varied with this option; from 0 for a very blunt almost
- square shape to 20 for a shape close to a set of crossed lines; with
- values around 5 to 15 giving more conventional star shapes.
-
- Dark mode.
- This sets limits on the allowed brightness of all the colours used. In
- particular, the background colour can only be black.
-
- Fixed background.
- Setting this option keeps the background colour constant; otherwise
- the background gradually changes colour.
-
- Solid colour.
- Setting this option stops the use of dithered colours. Although Grow
- Shapes is designed to display gradual colour changes which usually
- requires the use of dithered colours; if dithered colours are not wanted,
- and sudden colour changes are acceptable, then this option can be used.
-
- Background colour.
- This sets the red, green and blue components of the background colour.
- The display box at the side demonstrates the currently selected colour.
- There is a restriction on the brightness of the background.
- For a changing background this sets the initial colour.
-
- Speed.
- Rate of picture movement. Slowest 1 to fastest 10.
-
- Default.
- This resets all the configuration values back to the original default
- values. These are the values used when there are none set in CONTROL.INI.
- Although the default values demonstrate all the shapes and the complete
- range of shape sizes, they are not intended to be a preferred set of
- configuration values.
-
- Random Select.
- This randomly selects a set of configuration values.
- This option can be used to quickly test out a large number of
- configuration values.
-
- =====================================================================
-
- Password option - password maintenance program
- ----------------------------------------------
-
- There is a separate program, PWMAINT.EXE, that can be used to set and
- alter a password. Once set the password applies to all PJB Software
- screen savers. A saver cannot be terminated except by keying in the
- correct password. A password need not be installed if not wanted.
-
- (Note that the Microsoft screen saver password system used by most
- screen savers cannot be used with the ones in this package.)
-
- PWMAINT maintains a control file in which an encrypted version of the
- password is embedded. PWMAINT creates this file when the first password
- is set.
- When using PWMAINT the current password must be entered before a new
- password can be presented.
- Nearly all the keys on the keyboard can be used as password characters.
- Ctrl and Alt can be used in combination with other keys.
- Left and right mouse double clicks can also be used as characters.
- A password can be from one to twenty-four characters long.
-
- When entering a new password you will see that a bracket character must
- be entered before and after the password.
-
- The allowable bracket character pairs are
-
- curly brackets {}
- square brackets []
- parentheses ()
- point ..
- slash //
- back slash \\
- colon ::
- semi-colon ;;
- less/greater than <>
- number sign ##
- quotes ""
- apostrophe ''
-
- The bracket characters are not part of the password and are only used
- when entering a new password. They are not used when ending a screen
- saver or supplying the current password to PWMAINT. This system allows
- PWMAINT to be run without having to use the mouse.
- Curly brackets are the default bracket characters
- Examples of the the use of brackets to enter a new password:
-
- A} password is A
-
- {{} password is {
-
- /f/ password is f
-
- </> password is /
-
- } remove password
-
- :: remove password
-
- Note from the last two examples that the password is removed by entering
- a new password with zero characters.
-
- There are three special modes which can optionally be applied,
- separately or in combination, to password entry when ending a screen
- saver:
-
- Immediate entry
- The first character can be entered before the password entry box
- appears.
-
- End on last character.
- As soon as the complete correct password has been entered no more
- characters are requested and the screen saver ends.
-
- End on first wrong character.
- As soon as a wrong character is entered no more characters are
- requested and the screen saver continues.
-
- As an example, if Ctrl+Home is chosen as a one character password and
- all the above three modes are set on. Then if Ctrl+Home is entered the
- screen saver ends immediately without the passord entry box appearing;
- if any other key is pressed the screen saver continues uninterrupted; if
- the mouse is moved the password entry box appears.
- If all three modes are set off then, on ending a screen saver, the
- entry box will always appear and password entry must be terminated by
- either clicking the Finished box or entering Alt+F (if the password
- contains no Alt characters).
-
- PWMAINT can be placed anywhere on your hard disk.
-
- By default the name of the control file is )-ctl. The file always
- resides under the WINDOWS directory. If you wish the file to have a
- different name, use Notepad or another editor program to place an
- entry in CONTROL.INI as follows -
-
- [pwctl]
- file=myname
-
- PWMAINT will then create and use a file with the supplied name.
-
- Deleting the control file will remove the password. Om entering a new
- password PWMAINT will recreate the control file. So if you forget the
- password delete the control file and then enter a new password.
-
- Remember, the use of a password prevents someone who does not know the
- password from ending the screen saver and observing what was being done
- just before the screen saver started. It does not stop someone else
- using the computer, since this can be done by keying Ctrl+Alt+Del, or by
- switching off and back on.
