- ------
- This function has been ported from Fractint. It is a variant on the midpoint
- displacement technique - ie. set the colour of each corner randomly, then
- set each corner of each interior rectangle to a value based on the
- surrounding corners plus a random variant (the graininess value, the amount
- of which you can change). The display looks wonderful when cycled but this
- needs a full 256 colour programmable palette. You can improve the display
- significantly by using !EditPal to design a suitable palette.
-
- Alternatively try the Landscape palette and one of the 3d transforms. Due to
- the recursive nature of the function it stops if you press Adjust (no
- background plotting).
