Looking for something new to do with your spare time?
Then try TROYIS! I recently found this game online, and it's quite interesting. The idea is to move your knight around the board, landing on all the white squares (they turn coloured when you land on them) within the time limit. Yes, a new challenge for all you blitz players! The full version is available for a fee (US $19.95, lifetime access), but you can play for free up to 15 minutes per day (which, in my opinion, is more than I can fit in my schedule anyway). Try it for yourself, and if you get really good at it, challenge friends!
