Stream from October 9, 2023 at https://twitch.tv/sphaerophoria

Today we were looking at rendering optimizations for my framebuffer renderer. This started pretty slow, and we saw around a 60x improvement by the end. There's more that could be done, but for now this is plenty good enough. We then started looking at processing keyboard input, and implemented a pause/play for the bouncing ball demo

Code eventually available at https://github.com/sphaerophoria/stream-os
