Angular Power Transmission

Hey all-
This might be a slightly obscure question, but I've been looking everywhere and haven't found an answer.

I'm designing an off the wall drive system, and I need to transfer power through gears or some other mechanism 45 degrees. I've looked at flexible couplings, and joints that can be put into shafts, and I'm not too happy with these. Does anyone know if a gearset, much like bevel or miter gears, that transfers power at 45 degrees, rather than 90, is available anywhere?

Thanks a ton!
