An absolutely stunning idea for charity events, what an awesome way to visualize donations, credit the donators of any amount, and make you see the "big picture" that every donation amounts to! Hats off, you might want to approach other charity events with this idea, I'm sure people would love that concept!
Also the Diggy diggy hole background music is a nice touch, I'll admit it took me a while to realise why the tune sounded familiar haha
