Apple II 256 byte demos for Outline 2024

For Outline 2024 I submitted two demos, both "Bubble Universe" variants.

Notes

A lo-res (40x48 15 colors) zoom in on the bubble-universe, with some panning and sound. The big challenges here were generating the 256 entry sine and cosine tables, as well as the color-fade lookup table.

Notes

A hi-res (280x192 6 color) view of a subset of bubble-universe where the I paramater is fixed at 1. With some sound too. This uses the ROM HPLOT routines, but custom clear-screen (as the built in one is way too slow). Challenge was making the 256 byte sine and cosine tables. Was trying for 128 bytes but really 200 was the minimum. So added some features, like altering J on the second half of the cycle, and changing the background color.
