The first thing I made with my Ti Launchpad. It's just a simple dice roller with 2 buttons; one for 6 sided, and one for 20 sided.

The only trick here was the way the two displays were multiplexed, because of the lack of IOs. with both an NPN and PNP transistors, I was able to source current to one at a time depending on whether the bases were pulled high or low.
