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 that 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 maintain 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 Server is good for graphics, but I need to see if I can make use of other crunchers for code.  Any recommendations?
Loader: Not written, but that will be pretty easy to write when the time comes.
