## Notes

Interview with Petri Purho: liquids fall then spread and swap by density; gases rise; fire ignites random neighbors; wood burns then disappears; 64x64 chunks with dirty rects; bottom-up updates in four checkerboard passes; pixels may move 32 px beyond their chunk; pixel rigid bodies split as pixels are destroyed.
