This might be a good moment to drop a thing I made last year but never shared the link for. It's a bitmap editor that outputs Apple ][ shape tables.

Apple ][ shape tables were a rarely-used vector drawing technique -- rarely used because they were fairly slow to render and there wasn't great tooling for making them. High level of difficulty plus poor results... it was almost as easy to write blitting code, even with the odd Apple ][ video memory layout, so most games ended up doing that instead.

Anyway, if you are curious about shape tables, here's a thing for you.
