Movies: CRAZY (a neat quebec film). Recently watched don jon, the intouchables, and Django unchained.
Music. Like the XX, Kyte, Grimes, Muse, and AR Rahman.
TV: I like too many things to list. Just to name a few BSG, Parks and Rec, the Daily Show, House of Cards, and Game of Thrones (read most of the books too). I recently watched Orange is the New Black and need to catch up on the now finished craze of Breaking Bad.
More seriously: my research, societal problems, how to apply science and technology to resolve societal problems (so many cool things on this front), philosophy/religion, how to be a better / more productive person, and how to stop thinking too much about thinking.
