Chris Miller wrote in with the news that SGI is holding a contest for "the most compelling OpenGL API demos as judged by a panel of visualization luminaries." Over $80,000 worth of prizes are being offered, including two Onyx4 UltimateVision systems. Complete details are available here.
I know we have some talented OpenGL programmers out there - so get to work and bring home an Onyx4! I'd love to see some action shots of that system and can always use more photos for the gallery. :)
