They are still on the go and an Italian firm has just started making a CNC type, with variable mounting holes, so you can vary the oval relative to the cranks.

Superb stuff
I did some testing about 10yrs ago with some singlepivot suspension bikes, and found that eggrings could eliminate bob, increase traction - really good.
We ran something on it in mbr, but I think everyone is so tied in to Shimano rings, it was never going to work. It's a shame. In terms of eliminating suspension actuation from pedaling forces it's a cool way of doing it - but people seem happier running over complex rear shocks that don't work on small bumps.
