Well, maybe you don't have students that are enlightened/freak enough?
I like Creighton's video a lot, especially the dramatic music together
with a deep dive into the weirdness of all that platonic world.
BTW, How was that "jellyfish"-part made, at about the middle of video?
And I liked also your Ulam primes spiral video. Please keep on doing these,
both of you!
Moreover, is there a more high-res version of the floretion video than
what is at Youtube: http://www.youtube.com/watch?v=GKL4Lkw-rU0
And what would be the best tool for doing a video with combinatorial trees
growing, branch by branch? Or various manifestations of Catalan structures
