Tetrahedron. Use mouse to change direction rotation. This is my base for doing a "hyperbolic paraboloid" https://scratch.mit.edu/projects/717514187/
The program uses sine and cosine functions to draw triangles. To make the rotation work, code tells the pen to draw forever with orientation based on mouse position. My purpose here is setup a base for my hyperbolic paraboloid: https://scratch.mit.edu/projects/717514187/
