    love watching your videos, but HSB takes a hue argument in [0,360] not [0,255], in case you were wondering why your rainbows aren't periodic. keep up the good work!

    Could you do a video that goes over you're setup for programs like this? I.e. What editor/ide you use and what languages you use, and maybe a quick getting started guide? I love the vids and I want to do this stuff myself but I've never worked with this language before… just need a starting point

    Why is it so slow? I would assume it would be instant.

    Daniel I've recently discovered your videos. Amazing stuff! It really makes me wish I was better/understood math better, but I'm going to school for that. I love programming visual stuff like this so these are great!

    HSBs H goes from 0 to 360, so you may have noticed it changing from blue to red (255 is a bluish color). Just pointing that out!

    To be honest I dont understand shit on those formula.

    I may have ignored this on my school, didnt knew it was important.

    What should I study to be able to understand this?

    This angle is an approximation of (360/ Phi^2) or (360 / (Phi+1))
    Phi = Golden Ratio = [ 1 + Sqrt(5) ] / 2
