For those of us who seek more active entertainment, I would like to recommend Hyper Dash from Wild Planet Entertainment.

Hyper Dash uses an electronic plunger (for lack of a better word) that plays music and calls out what targets to hit. It calls out colors or numbers for the targets, and the plunger identifies them by radio frequency identification (RFID). It makes you think on your feet and run quickly to get to your target.

You can get Hyper Dash at the Wild Planet site for about $24.95 USD.
