We're counting down to euromaxx clipmania's 100th edition, and have come up with clipmania 100 - a selection of the best 100 internet videos. We're airing one a day for 100 days and if you write in with your favourite, you could win a Leica digital camera. Today's show features number 19, which shows a flashmob performance by the Berlin State Ballet for their new show: "Oz - The Wonderful Wizard".
