I just found one called Screebl. It basically sets your phone's screen timeout to the minimum and keeps the screen on depending on how you hold it. It is customizable as to the angle. Works really well.

Hopefully it will same some battery power. Search the market for Screebl if you want to try it. It is free.

Word is it "made it to the final round of the Android Developer Challenge 2"...

Im still deciding but looks promising.
