    I teach 9-year-olds programming and used a tidied up version of this to show them how to figure out how something works. They loved it! Thanks! I've added a bit of gap between the strands to make it easier to understand, and I think it looks good. Like Math.max(180*S(a-1.2),0).

  • oh would you look at that, now i can say i've made a dweet! (the performance isn't very good from what i've experienced, but the visual turned out well, so make of it what you will)
