µTetris MSP430
This is a micro Tetris.
It features a fully functional Tetris programmed in C with the free TI Code Composer Studio.
It also has an LED backlight that can be turned on
and off. The system without the backlight uses less than 1mA. The CPU is in low power mode over 90% of the time. The program is completely
interrupt driven to preserve as much power as possible.

It is built up with a Nokia 5110 cell phone LCD and an MSP430G2554 ultra low power microcontroller from Texas Instruments.
The advantage of the cellphone display is that it uses a very small amount of power (about 800µA).
The circuit is wired up quick and dirty and then put into a neat little case.
You get 2^(n-1) points for n rows...
