Looks like it needs to be added to this list. http://forums.thepaceline.net/showthread.php?t=137041

I guess the 12th post wasn't the original Rotor cranks. (!?!?!?!?!?) In my single days I would have bought that just to find out how it does (or doesn't) work.

Looks like took them a few years to figure it out that the way to go was to oval the chainrings.

When this was posted yesterday I spent some time Googling "Rotor" and "eccentric chainrings."
I came away with the following:
-Rotor produced some funky stuff over the years.
-there's a bit of confusion out there between oval and eccentric.
I didn't find anything nearly as weird as the the OP's CL image, though. Not even the z-shaped crankarms.
