Very, very busy at work and not feeling much like blogging after a 12-hour work day, but to tide you over in the mean time here's Loops of Zen.
It's a browser game, and it's simple. You get a board of tiles, each with lines and connections to other tiles, and you rotate the tiles until there's no dead ends on the board - every line must curve back on itself. Surprisingly satisfying and easier than it initially seems.
Go play it now.
