Portable Movie Theater on a Trike
Mister Jalopy's Urban Guerrilla Movie House
"A Schwinn Town and Country adult tricycle with a Lumenlab-style projector on the back. Inside the wooden box is a stripped 15" PC LCD monitor and replacing the meager florescent backlight is an awesome 400w lamp that is bright like welding. Add a reflector, a couple of fresnals lens and a homemade focusing triplet lens and you are ready to bring the party to the people."

Ohhh... I dunno about THAT center of gravity!
