Retro awesomeness (June 8, 2016)

I've been writing a standard C library for the Nintendo Game Boy system over at Delwink, and now I've got a working Pong prototype game. It still needs some more features yet to be added to the library, but it's a playable game! Check it out on GitHub, or clone https://github.com/2mac/gbpong.git.

Fun for hackers (May 28, 2015)

I made a new program in response to a challenge, and it has turned out to be a useful learning tool. See it on GitHub, or clone https://github.com/2mac/ttt.git using Git to check it out. Be sure to first read the README file before getting started.
