The OpenToonz/Tahoma2D animation program lets you make brand new visual effects using GLSL (OpenGL Shading Language). Luckily for me, it's a 2D program and not 3D, so less math I have to relearn. Gonna be diving into a bit of linear algebra, trigonometry, and some geometry to learn how to manipulate vectors and matricies. This ought to be fun. And even if I don't really use Tahoma2D in the end, it would still be beneficial for me to know.
