That's neat. Another idea is to use the black plastic "demo" platforms that bike shops use for test rides; they essentially transform any SPD pedal into a platform. I hear they're a good temporary solution (nothing you'd want to leave in forever; better to get a pair of dedicated platform/clipless pedals like the M324s I mentioned above)..
