Cylindrical screens. Because.

While most people want to be surrounded by a widescreen picture,
DynaScan Japan went ahead and developed a 91-inch cylindrical LED screen that one can actually surround.  It will dispay both moving images and still images, and will set you back around $900K.  It will most likely show up in over-budgeted exhibits and obnoxious installations with signs that say, "Look!  This cylinder of video love cost almost a million dollars.  A million dollars!"
