Wasn’t all that difficult, but I got my peyote substrate sketch working again. The only interesting thing I discovered is that the Python
cairocffi module doesn’t work particularly well with
cairocffi has this weird bit where it stashes data buffers in an internal cache to help finalize external data garbage collection. Unfortunately, this conflicts with
pygame’s locking of Surfaces before blitting to the screen. Switching back to
pycairo was the resolution.
Anyhoo, debugging the issue forced a reintroduction with peyote. The codebase is surprisingly although a bit hackish. It’ll be fun to clean it up, modernize it, and generate some new sketches.
