Portal 2 Sixense DLC -- and actual Hydra controllers -- available from Steam

If you're excited about both motion controls and Portal 2 -- or you're so eager for more Portal 2 content that you're willing to pay $140 for it -- the new "Sixense Motion Pack" DLC is available for download on Steam, including six new levels that feature stretchable blocks.

Of course, you need the Razer Hydra motion controller device itself to be able to play this content. And you can get that through Steam, as well. No, really. You can order a controller through Steam. Who knew? The controller comes with the DLC and a free copy of Portal 2. Which you'll likely be giving away, if you're the Portal-crazed person we mentioned at the top of the post.
