I (@kriblo) couldn't sleep... I've got a cold (buuhuu) This is more or less a recreation of a visualization of sine and cosine found of Wikipedia: https://en.wikipedia.org/wiki/Sine All code by me (@kriblo). I was planning to make this into a tutorial on how this can be used in Scratch... maybe someone wants to take the baton? Update 20 Nov 2019: For now, press s for a very simple example of how you could use this. Look inside at the sprite Rocketship.
