You can scroll through the program which starts with Fibonacci Blocks, then proportions with calipers 1:1, 1:2, and 1:1.618, then we make our own calipers, discuss the progression of Fibonacci blocks — the bigger they get, the closer the proportions of adjacent blocks are to the golden ratio. Finally, each group gets a golden spiral to color.
