Money Pizza is an promotional concept for an imaginary pizza chain that sells a $5 pizza. The magnetic fridge-based coin keeper holds $5 in change. As its creator, artist Matt Brown, says, "The concept eliminates the shame people feel when they pay for something all in change. No counting involved with this, both cashier and customer know exactly how much money there is on that pie."
Of course you're still left scrounging for the tip. [via EMD]
