Devil's Picturebook by Derren Brown has several. Pure Effect has the same ones, but in DP, you get to see them in action. Personally, I think Invisible Deal (which isn't a force) is one of the most interesting effects around. Your request was a bit ambiguous, but DP has some good forces, even if they don't fit your requirements.
