What we really need us a “modulo” division conversion.

I’ve worked out a way of connecting a linear conversion, through a scale conversion, and a sin and cosine conversion, and then a vector angle conversion, which allow what I think this fellow is after, you can go round around a circle 360, 720, 1080 degrees linear, but through the conversions finally “vector angle” ( or arctan2 can also work) makes this go from 0 to 360 over and over. It’s bizarre but it functionally works like a modular division function.

So you could build one of these gadgets with a divide by 36 and it could be bribed to count from 0 to 9 over and over then you run that into the selected field of a switch function or something. I really need to find the file server so I can share files with you guys. There are a lot of really cool things you can do with conversions.
