Playing With Soh/cAh/toA

We're doing an abridged version of Zach's 'algorithms for animation class' at SFPC, and the past two days have been diving into trigonometry. The challenge for the morning was to make a John Whitney inspired animation, exploiting the awesomeness of sin/cos/tan/arctan. 

I've also been playing with Lissajou patterns on the oscilloscope from FM and AM synthesis in Max - amazed at how simple and beautiful they can be!
