This circuit is very similar to the Multi Phase Waveform Animator
(MPWA) from Electronotes. There are several other instances on this
theme out there. Off the top of my head:

http://www.cyndustries.com/modules_sawtooth.cfm

The very notion of "voltage controlled fat" makes me chuckle.

Richard Brewster pasted a link on the ModularSynthPanels group with a
sample of his MPWA:

An official MOTM version of this beast would be most welcome.
