Thanks for letting me know, I'll be sure to look into it. I'll likely be taking a visualization class as a music tech minor as well, so its good to know there are a lot of opportunities to improve.

Tulane has a Data Visualization class, which is primarily in Python. OpenGL (in python) VTK and a bunch of other tools. It can count as an upper level course for CS major if you ask.
