For about $35 USD you could make your own WiFi Can TV receiver. This one was build for the village of Bourem Inaly, Mali. Its part of a project to help the community have a better source of information and entertainment. Check out how easy it looks to make one -> VIDEO->
“One goal of the CanTV project is to make it possible to build the CanTV receivers or TV cantennas (antennas built with cans) using locally using locally available parts, with the exception of the $25 audio/video receiver currently imported from Canada. Also, the TV cantennas have been designed so that a local technician can quickly learn how to install them without special tools. The radio station already has access to television broadcasts via satellite, and a TV over WiFi transmitter installed in August 2005 by Moussa Keita of Geekcorps.”
