That fancy hub posted by smc02 looks cool, but probably wouldn't be much
good on a unicycle. Radially spoked wheels are no good for a wheel that
has to transmit torque from the hub (so it's really only useful for the
front wheel of a bike, and even then only if not using any form of hub
braking).
There are similar hub designs around that look unusual, and still have
the advantage of using straight spokes (less chance of spoke breakage -
they usually break at the hooked end of a conventional spoke where it
goes through the hub flange), but are laced in a suitable way for a
drive wheel, so could be used on a unicycle. Advocates of these hubs
claim that fewer spokes can be used because of the stronger spoke/hub
interface, but I suspect that rim stability is probably more of a
problem on a unicycle (with the higher lateral forces than on a bike
wheel) than spoke breakage. A unicycle hub built this way would look
pretty cool I think.
There are various designs around, but here's a picture of one I found
quickly:
