Going to be drawing patterns during a weld using a high powered laser. This pattern determine the shape of the laser point. Not sure on radius of laser output. Probably mm/um in size. Won't be able to "see" the pattern. Anyway, I suggested default pattern chains: 666, 420, 69. So far nobody really likes those options. Maybe I will do emojis.

I think I will need to optimize pattern distance between points. So I might get to do a real algorithm for this. I have not seen the requirements for this part yet. But I am thinking maybe A* for shortest path to next point. Or maybe some flood fill. Could be fun. It would be wild to use a gaming algo to melt metal. lol
