Sorry Brett, I couldn't really take you seriously after you picked up a deck of cards, started shuffling it and casually commented 'for this trick, I'm going to use a deck of cards.'
In all seriousness Brett, I would recommend not using the hindu shuffle at the beginning. It looks fishy, seeing as that isn't what somebody naturally does at the start of the trick. If you wanted to show the deck as blue, spread them out. Seeing as you can't, don't. If you don't draw attention to the colour, the audience won't question it.
Synth, great job. No idea how it was done whatsoever, and I actually laughed out loud at the end. Brilliant. 'Nuff said.
Actually, it wasn't quite perfect, I'm afraid. Sadly school has just broken up for christmas, and I can't quite remember why. If I remember, I'll edit.
