I saw this over at design you trust and thought it such an amazing idea that I am suprised you cant buy these in the shops already. I can however see some flaws in the idea, namely what if somone sees it lying about on your desk and throws it away; seccondly it would only take a serial sandwedge theif to notice its an illusion once before they strike again. Still it is an incredible consept, slightly flawed but all together quite a marketable item I think.
