Alien Swarm was released for free on Valve today!

This is a great video of a track test of Campagna Motors T-Rex motorcycle/trike. It starts at $50k, but it looks like so much fun!

The unbelievably fast Ariel Atom. I think it is a great looking vehicle, and it seems that it must be very rugged.

Prepare to be inspired. I think it is incredible how one scene transforms into the next seamlessly. I'm not sure that they should even be called 'scenes'.

Sniper is one of my favorite classes in TF2, and this video is probably the most humorous of the "Meet the [Class]" series of trailers for TF2.

Cool video of employing programmed quadrotors (sometimes called quadrocopters) to lift and move pieces of wood.

Clip highlight(s): time travelers from the early 90's, duck stuffed animal, upside-downedness
