Even better, if you can come up with 5 flippable distinctive items you can simply set each as a bit and shake and flip them at once. d4=2 bits+1, d6=3 bits rerolling 0/7, d8=3 bits+1, d10=4 bits rerolling 0/11-15, d12 similar, d20=5 bits rerolling 0/21-31. I suspect that most gamers could pick that up pretty quickly with just a bit of practice.
