I tried doing my own finger cursor and it ended up just looking creepy - and you couldn't really see taps. I'll take a serious look at this one though. Thanks!
Using a finger image will always look creepy cause it is lifeless, kinda like holding a chicken leg and pointing with it.
We learned this firsthand with this unsuccessful demo video here: http://www.youtube.com/watch?v=tV4VGrn_Nuo
this finger shows tap action! try it for your next screencast
