Yeah Nokia research lab showing off what looks like accelerated OpenGL ES at 2:06 and 2:09-2:13 in this video.

(p.s. Don't post the email addy here cause spamcrawlers might find it)

(edit) Note that the video shows a higher resolution on the projector than on the N810, so they may be rendering the projected video on a PC/laptop. Also note that the GL apps on the N810 are only isplaying a few polygons - i.e. the whale is displayed but no sharks, and there is only one building showin on the rotating green rectangle at 2:09
