[SML] Rear projection

[smashwolf at gmail.com]

you can fix hot spots in software!  Use video mapping software, place 
the projector OFF AXIS, so the hot spot is not visible, and correct the 
geometry with the mapping software.  I have done this with a product 
called MadMapper, and a video capture device like a BlackMagic Design 
Shuttle on a MacBook Pro.  The projection source will be out of view, 
and you can use one projector then to map multiple different geometric 
shapes to project through at once.  MadMapper is cheaper , but I have 
found ArKaos Media Master to be much easier to use if you can afford 
it.  Media Master is also a PC app instead of OS X.

There are many different alternative projection fabrics that Dazian and Rosebrand have to offer.  Heck, for Halloween, I use a cheap, dollar store grade white plastic table cloth to cover my living room window and rear project on it.
