Tiburcio and his daughter Helena have an interesting tool for learning when an online purchase has been made from their web store — an Arduino-controlled Wario toy. Tiburcio explains:

I wanted something nice to have at the office that tell us every time someone make a purchase on our game. Every time we make a buck Wario rings the bell and flash his greedy green eyes. If we made a lot then Wario shoot smoke from his ears!

You can check out Wario in action in the video, including the sketch that allows Tiburcio’s Mac to communicate with Wario wirelessly via an XBee module.
