    This was amazing to watch! Couldn't nearly keep up, but I'm so happy you posted this. I have a serious crush with geometrical shapes like these, there's something very pleasing about them. Thanks for posting and being so energetic! 🙂

    Would you challenge using anti-aliasing tech to draw a line, arc, circle or whatever on none vector graphic map?

    How would you clean up the close? The line can be taken away but it's still technically a problem. I have it oscillating the values with a nice sin() map, but the line really kills the visual aspect of it transitioning.

    Hi Dan,
    thank you for your great work. It inspired me to create a 3D color cube in processing. If you like to have a look at it I created a fork on GitHub https://github.com/ElLoko/ColorCube3D
    Cheers, Timo

    watch all of your videos and sadly I'm here with visual basic and c#. how do I start with js?

  21. Aya Sakuraba Avatar

    Actually, you have a pretty decent french accent, it was completely recognizable. Thanks for the fun mathematical video. Keep up the excellent work, and your contagious good mood ! 😉

    Link for wikipedia is broken you can still easily find what you wanted just had to comment

    Please, calm down. Some of your antics detract from your message.

    I have a Ruby Shoes program like this in a gist here. https://gist.github.com/DouglasAllen/dd978dbf533a9d30302490655985a209
    I've had this for a long time and even before that did one like this in BASIC on a Radio Shack TRS-80 Model I level II. That's why I'm brain damaged when it comes to programming.

    You should write an extension for VS Code since it is all javascript. see http://code.visualstudio.com/

    Your pronunciation of "René Descartes" was good 🙂

    If I watch you coding everything seems to be so easy. It makes me a lot of fun 😉 Thank you Dan doing this

    Super cool to see a video about this. Like all your other video's I love it!
    A while back I did some experimenting with drawing 'roses': http://codepen.io/pimskie/details/YGZLaW
