Sadly, innovation in teaching is neither a priority in academia (since it is not research) nor in the industry (since it is this kind of activity that ).

I wouldn't say there is no innovation though. There are science-based games (https://github.com/stared/science-based-games-list; it was here some time ago: https://news.ycombinator.com/item?id=14661813). I started collecting interactive machine learning, stats and maths: http://p.migdal.pl/interactive-machine-learning-list/ (a lot of things; of course, Immersive Linear Algebra is there). Most of these projects are side projects, though.

Also - I had a plan to extend the quantum game (it is nice to hear you enjoyed it!) to more particles... and then, a full course, with experimental widgets (e.g. showing interference, then explaining it, then giving space to play with it). With some framework (maybe $, but I care even more for collaborators and deadlines), I would love to continue that.

What are your projects?
