Utilizing a proprietary system based around an "axisymmetric free-form-surface lens," the camera could shoot video at horizontal and vertical viewing angles of 360-and-50-degrees, respectively; the images could then be projected in the same range by a separate unit.

That was back in 2007 and nothing has ever materialised from them.

I am trying to help a company involved in the events sector to seek and find a current solution where they could offer a walk-in 360 arena (tent or whatever) and immersive world for an audience to view a dramatic show utilising 360 degree projected switchable backgrounds.

Does anyone know of where this technology is going (is it doomed?) or of any other viable solutions that could be made and put together using today's technology?
