I found a link to this on buzzfeed, but it's worth repeating here with a little more info.
Ennio is an Italian comedian who has developed a unique "quick change" act that includes over 300 characters. Inspired by cartoons, the characters are done with costumes made out of cardboard, with some costumes morphing into others during the act. He first came to prominence at the Edinbourgh Fringe Festival in 1989 and has won several awards for his work over the years.
His website is here. It's a fascinating read - I had no idea one could do so much with markers, cardboard and gaffer's tape.
