Another early demonstration of the Fnk interface. This video shows some math-based animation being applied to a circle, using the newly added node content editing feature and graphic creating/rendering nodes. It may be difficult to understand for people who don't know how and why Sin and Cos functions are used. I also tried using as little space as possible, so the resulting patch looks like a mess.
