Seamless Video Walls
ahfoo writes "A company called Seamless Display is shopping around a new way of hiding the seams in video walls that mostly relies on modifiying video drivers to achieve its effects. According to their press release they hide the edges between monitors with a bit of plastic film and compress the video at the edges to produce a more or less seamless image. " Really bizarre, but it looks interesting.
...that was mentioned on Slashdot.
PHEM - party like it's 1997-2003!
OLEDs are almost there, they are already being used in small portable devices (cameras and phones). They can be scaled without the fabrication issues that hit CRTs and LCDs. There is a good chance that OLED screens will be the first consumer-ready wall screen system (the current best of breed being the projector).
But this looks fun, and it may be a good stopgap. I'm wondering whether it can be used to build (for instance) large LCD monitors for PCs...? I once had a portable that used two B&W LCDs to achieve a larger display area, but I've never seen this done with color LCDs.

www.draper.com Back when I installed Air Traffic Control simulators we used Draper screens. I was looking at the Draper site and they said they had seemless displays and this was about a year ago. We could get pretty seemless with the large screens that we had.
I saw a demonstration using a beowulf cluster (well, part of one) that was rendering a moving 3-d CAD model. They just threw the projectors so they were somewhat aligned, used a webcam and had one of the nodes look at the overlap and correct for the projector's misalignment in real time. ~20 other CPUs were doing the rendering, but it only took one to make the display come out right. I would imagine the same thing could be done for a rear-projection screen. As long as the projectors didn't get jostled after being observed by the computer it should work fine.
