- 1-5: select different spirals
- A,S,D: grow, shrink & reset to golden spiral
- Mouse movement: does stuff
Sunday Sketch inspired by this Vi Hart video. Quads created by vertices at intersections of two groups of opposite golden spirals. Number keys change the number of spirals in each group, always to fibonacci numbers (3/5, 5/8, 8/13, 13/21 and 21/34). It's easy to fall in love with the number phi when you play with this stuff.
