I don't see openFrameworks mentioned here: http://openframeworks.cc/

Probably the most comprehensive open-source creative coding framework. Maybe most helpful for familiarity with graphics programming / OpenGL, but it really extends to all types of possible interactions. Maintained by an awesome group of people.

OpenFrameworks has nothing to do with _modern_ C++. It’s a framework for laymen artists that happens to be written in C++. It won’t teach you about move semantics, lambdas, unique_ptr, for-in loops, etc.
