Found out about this when someone linked to the Mathematician's song in the comments of a Computer Science Theory blog. Intrigued, I picked up the DVD from cdbaby. Fantastic musical. The songs are catchy with tight harmonies. The arrangements resemble clever showtunes in the lighter moments and Ben Folds-style piano rock in the harder moments. There is very little dialogue or shoe leather- the animations fill in the gaps and connect each of the characters during and between the songs. The animation is whimsical and a bit absurd in parts, but is usually symbolic or indicative of events in the story. Fantastic work, gentlemen. You have won me over.
