Oh cool! I found that in TestTube (the Youtube labs), there is a feature to make a stereoscopic 3d video out of two videos on your channel! So I quick opened up 3dsmax, did a rotation around the classic teapot (which had a bit of texturing), and rendered two cameras side by side.
They say in their settings that they do NOT support the theater 3d glasses (the polarizer lens type). But they have added capability for 3d tv's and computer monitors. For us unrich people though, we can use the classic old-school red and blue glasses and view them. Or they have options to change the colors of your classes from red-blue to magenta-green, blue-yellow, or none. See all the options here: http://www.youtube.com/select_3d_mode.
