To bring awareness to the Milton Keynes gallery in England, British Artist Tomas Georgeson hid a check for £8,000 ($12,500) inside the gallery. To claim the money all you have to do is find it...but while you're there, you may as well check out some of the amazing modern art too. The gallery offers free admission and some of the best international contemporary art in the UK. Think of it as a treasure hunt for both your wallet and your mind. Good luck!
