Steam's Big Picture Mode has officially launched, allowing you to buy and play games, chat up your friends and browse the web from the comfort of your living room couch, using only a gamepad. Valve have decided to celebrate the way they celebrate any big event - with a sale! Multiple controller supported games have now gone on sale, with a good variety showing up: everything from Counter-Strike to Train Simulator.

Speaking from experience, Big Picture Mode is indeed a joy to use, and Valve have made some smart moves in the space that outdo some parts of the interfaces of actual game consoles originally designed for TV, particularly their brilliant "Daisywheel" text input system and "first person browsing". You can get caught up on the Big Picture over here and pick up some games to use it with over at the Steam store.
