Mostly playing FTL (a really awesome indie game that I definitely recommend you all try if you like roguelikes), designing a few mechanisms on Minecraft (some nice, simple frame doors), spending time on Tumblr, watching Battlestar Galactica, writing, watching Direwolf20's YouTube videos... oh, and convincing my friends that the Feed The Beast modpack is better than... the other technical modpack whose name shall not be spoken in my presence. Believe it or not, that's actually worked out really well for me.
