I got the mechanical part down. I sat there for a day or so and thought about how my hand moves, and why it moves as it does. The hard part wasn't figuring out how to make it work, it was cutting the material without messing up, as I just moved to a new house, and the garage hasn't yet been converted to a shop and all my tools are still hiding in boxes unknown.
I ended up using a dremmel, a really heavy vice, and a really steady hand for everything.
I'll post some pics later on once I actually finish making it. So far I have the first, middle, and ring fingers made, and they move and bend just like real fingers. Oh, and they are solid, unlike many where the fingers are a single segment pinned to two segments, pinned to a single segment.
Eventually I hope to build the whole body, but I have neither time nor money for such an endeavor. Perhaps once I'm finished woth school, have a regular working schedule, and a decent paycheck I can tackle that project...
PS, thanks for the recommendations on the PIC's. I'll be looking into them sometime later this week.
