NVIDIA 3D Vision PCs and notebooks, running Firefox 4. If you're rocking an NVIDIA GeForce GPU-equipped machine, sporting driver release 275 or later, a 3D Vision monitor, notebook, projector, or DLP HDTV, and Firefox 4 with streaming HTML5, you've got access to all the 3D goodness YouTube has to offer -- given you're not trying to access content via a standard YouTube channel, as the outfit's HTML5 support is still limited. And don't forget, you'll need your active shutter 3D glasses handy, too. So, if you fit all of the aforementioned criteria, check out the demo video after break (and make sure to hit the HTML5 function under options) -- otherwise, feel free to go on using the old cyan and red method for viewing YouTube in 3D. Full PR after the break.
