I've recently come across something called Q-rings. They're ovular or elliptical shaped chain rings! The purpose?
This technology supposedly eliminates the dead spot in the pedal stroke but lowering the number of teeth in the return stroke (pull up) and increasing the number of teeth on the power stroke using the same chain ring.
The mere shape of the chain rings (in theory) does this effectively. I have yet to prove this through experience, but am completely eager to give it a try. Notice the oblong shape. That's not a disfigurement of the photo. Nothing's wrong with the computer screen. It really is stretched out vertically in this photo.
