Inexpensive Immersive Projection
Low cost 180 degree visuals? Perhaps.

From the recent Virtual Reality Conference ( VR 2008 in Reno, NV, USA, March 2008 ) comes a low cost projection project which could help this hobby realize greater than 180 degree visuals. I'm hoping it's not blurry or stretched, but the video looks promising.
A quote from the paper:
"Our goal is to build an immersive projection system that meets
these requirements: uses minimal, affordable hardware; takes advantage
of existing surfaces for display; requires minimal setup and
configuration; produces a large field of view, greater than 180 degrees;
requires only a casual arrangement of system components;
avoids determining display surface geometry; supports real-time interaction."

They use a library called OpenCV (open computer vision library) for corner detection which helps to automatically calibrate the display. http://sourceforge.net/projects/opencvlibrary/
Looks promising. I'll have to tinker with this library.

Cost of 180 degree display
If you read the paper, they say the total cost minus the projector and computer was around $350. Of course, I would want a seamless half dome screen which would be difficult to make.
