TeleBall is an Arduino based retro handheld game console. You cannot buy it. You need to build it by yourself. It lets you play BreakOut in single-player mode using one device and Tennis for Two in multi-player mode using two devices communicating via radio.
TeleBall is pretty retro and very minimalistic: It features an 8×8 pixel LED matrix display, a paddle as game controller and one button. Therefore, the range of possible games is limited but you will be surprised how much fun and even zenlike meditation this kind of gameplay can bring you, particularly when you play Tennis for Two with a friend.
1.2″ 8×8 Matrix Square Pixel – Blue: Make a scrolling sign, or a small video display with this 8×8 square gridded blue LED matrix. Only 1.2″ on a side, it is quite visible but not so large it wont plug into a breadboard! 64 blue LEDs are contained inside the plastic body, in an 8×8 matrix. There are 16 pins on the side, 8 on each, with 0.1″ spacing so you can easily plug it into a breadboard with one row on each side for wiring it up. (read more)
