First I made the inverse/flicker routine for one sort of optical illusion. =
 Now I've made another which draws dots on the corners of a checkerboard to=
 make it look like it is warped.  And I optimized the heck out of that so t=
hat there was extra CPU to add a scroller using the empty spaces inside the=
 squares, billboard-style.

It's not terribly fast, but it's optimized enough to not be terribly slow. =
 Double-hires is a very tricky thing, especially when you're trying to main=
tain the illusion that you're updating the whole screen!

Obligatory scroller: check.
At least two different routines: check.
One or two variations on the routines so they don't old within the first 15=
 seconds: check.
Music: Need music.  Time to do that!
Crunch/Decrunch: 50% done.  The packbits implementation for Apple Game Serv=
er is good for graphics, but I need to see if I can make use of other crunc=
hers for code.  Any recommendations?
Loader: Not written, but that will be pretty easy to write when the time co=
mes.
