We'll start with a One Coin Flurry. My version was directly inspired by David Roth's Flurry Routine from his Expert Coin Magic, pp 23-25.
This effect can be performed impromptu, with a borrowed coin, making it ideal for casual performers. The modular nature of the routine makes it great for 'breaking in' new vanishes and productions. Roth says the coin should almost take on a life of it's own as it jumps around the body, almost out of the performers' control.
