Here's a video of a Mahdi Gilbert card magic show at Magic-Con 2012. Madhi's a 20 year old magician from Toronto, whose arms and hands are affected by a congenital condition. His sleights and routines are rather novel, adapted for his anatomical quirks, and his mastery is indisputable. PeaceLove, the magician who sent in this video, notes that the second half is better than the first. There are plenty of other videos of his work on YouTube, including this interview.
