Markus Gritsch posted his MSP430 LED Matrix toy in the project log forum:
I just did a quick little project using an MSP430 and two 595 shift registers to drive a small LED matrix display, suitable for beginners. Two push buttons are used as inputs and a buzzer is connected to a timer output to generate some tones. A resistor to pull up the reset line, a clock quarz to keep track of the time and a buffer capacitor for good measure are all the additional parts needed.
