Ever wanted to perform diminishing cards? The classic stand-up/stage version has the magician fanning a deck and the cards appear to shrink in size with each subsequent fan. Best known is the version based on an optical illusion but there are many more.
Steve Dushek offers an excellent gimmicked version that is at home on stage as it is in close-up. I really like it and it's not hard to learn and perform. You can read my review here.
