I'm an animation teacher and have been using this as an exemple in classroom for some reasons.
The computer generated transitions are very similar to a grotesque tween in Adobe Flash called "shape tween", that was very popular around 1998/99, for similarities with the MORPH effect in video.
It proves even the most tired resources may find purpose when in good use.
The best material from the NFB, though, is still in the works of the great Malcolm McLaren, in special his works on drawing audio.
THe results are eerily similar to 8-bit music, given the geometric shapes he uses.
My very favorite is the tour-de-force Synchromy.
