Elastic bands (thick, wide ones) make good belts. Larger belts can be made from surgical tubing. Shoelaces and even just good old cord works, too. Whatever you use, you want to make it stretch just a bit to get it over the groove in your pulleys. Make sure it doesn't have to stretch so much that there's undue stress put on the motors' shafts, though (for instance, when using surgical tubing).

I actually have some scrap aluminum too... ^_^
I guess I was thinking a belt needed to be..mm..closer to perfection than a shoelace. I guess I was overthinking it.
Didn't think of using a computer power supply. I have a couple of those laying around too. ^_^;;
Wow, these are great ideas. I'm actually seriously thinking about the clockwork motors now too. I think having 24hr, 1hr, and 1min sections would be cool. I could still incorporate oddly moving bits too.
Thanks everyone for all the great help and ideas!!
Oh, but one more note about powering them... How can I give them the right power? I think hooking a 9V motor straight into the wall might not be a good idea, so how does a power supply regulate this? Is there another part I need or can I figure out what the power supply does...? (????)

o.o I used to love legos when I was a kid. I think I
might have some of my old legos in storage. I think I had some kind of train than that had a motor, too. Even if it doesn't work well for all of it, it may be good for testing purposed and such like that. Nice idea.
