These are some demo programs for the graphics library.

To build: either "make", or by hand:

	camlc -o colwheel.exe colwheel.ml
	camlc -o showsort.exe record.ml playback.ml sorts.ml showsort.ml
 	camlc -o spir.exe turtle.mli turtle.ml spir.ml

To run:

	showsort	# hit any key to quit

	showsort 1000	# or some other delay, to slow down the animation

	spir		# hit any key to continue

	spir 176 7 -17.5 # or some other arguments, to get various shapes

	colwheel	# hit 'q' to quit, '1' to '9' to change the brightness
			# looks good in 256 colors only
