Several years ago I read an amazing scientific paper on the mathematics of Poi patterns, by DrexFactor – you can have a look at the web version here.
So recently I was thinking about it again and managed to plug some of the formulas into a Processing sketch:
I have always enjoyed emulation software for juggling, it’s amazing what you can do – juggle 100 flaming swords for example (or make an LED juggling emulator, like this one I made) Anyway, it turns out that there isn’t anything similar for poi spinning.*
Seems like there should be one.
*UPDATE: turns out there are quite a few. Thanks Reddit! Here is one of my favourites, done in Processing: http://www.kaiein.com/poi_auto_sim/
