Just grab a baby plate ( http://www.bhphotovideo.com/c/search?Ntt=baby+plate&N=0&InitialSearch=yes ), screw it to a 12"x12" piece of plywood, and pop it in a grip head on a C-Stand. I've done it countless times for turning LCD screens into makeshift prompters, mounting projectors, etc. You can also then use it to put lights on the ground, or on tables really easily (just flip it over!).
