so, i'm releasing 2 rather specific libs today. one is cannon-es, a esm port of cannon by @schteppe: github.com/drcmda/cannon-es (looked unmaintained, didn't bother making a PR) and the other is use-cannon, a super rough web worker bridge for physics in react: github.com/drcmda/use-cannon

山 - shān = mountain
出 - chū = get out (it represents two mountains stacked on top of each other, in ancient China, emperors exiled their enemies beyond the mountains, so nowadays exile has become to mean of “get out”)
