Notes
Remarks"L-Systems" is a type of fractal using rules of generation to produce self-similar space-filling curves. This implementation by Greg Harder is true to the original specification, and it's recommended that you look up the reference provided in the program. From a ZX81 standpoint, this one is interesting in that it uses our "QUIK" display mode. This is sort of a hybrid between FAST and SLOW; by mucking with system variable MARGIN and display timing, you get varying degrees of speed improvement traded off with dim or flickery displays. But at least you could see what was going on! No guarantees what emulators will do with this...
