- ===========================================================================
- FracBlank is yet another custom screen blanker created to live in symbiosis
- with Kickstart 2.x and the Commodities Exchange toolkit, similar to the
- `Blanker' program to be found in Tools/Commodities, just more wonderful.
- Apart from the usual job (turning the screen black after a given period
- of time to prevent the phosphorus of your monitor from burning in) it will
- draw some neat patterns while mouse and keyboard are inactive. Instead of
- bouncing polygons, the Amiga logo, the Boing! ball or other assorted items
- around the screen, real plane fractals (yes, real fractals) will be drawn.
- The algorithm employed comes from the September 1986 issue of Scientific
- American; some of you who are familiar with OpenWindows Version 2 (such as
- running on the Sun4) will know it from the popular `xlock' program. The
- patterns created may remind you of spiders' webs, lace or even the
- Chladnian patterns formed by grains of sand strewn across a vibrating
- surface. I haven't seen an implementation of this algorithm on the Amiga
- yet, so it was time to program it ;-)
