For the ILA 2004 (Aerospace Exhibition) in Berlin MediaScreen realised several innovative special solutions in the field of media technics. Beside a “solar tunnel” which was realised with a wide-angle-lens rear projection, three more projectors with wide-angle lenses and trapezium distortion were used to implement a half-ring projection. The visual and technical highlight of the exhibition was the first time use of the MediaScreen prototype of a 3D perspex hemisphere with a diameter of 2.8 m. Onto this projection hemisphere a specially animated image of the earth was projected using a 12.000 ANSI Lumen high-power projector and a special wide-angle optic. Additionally MediaScreen realised two projections with rear-projection screens with a format of 2.4 m x 1.8 m on both sides of the main stage. One of these two projections was a 3-D presentation on polarizer basis giving an impressive inside experience of for example the inside of the ISS station.
