Video-Whale Project
The video-whale project is an implementation of video-wall which exploits the combined power of GStreamer (www.gstreamer.net) and Xinerama. With it, four monitors are controlled by one machine, and a LAN of four machine controls a 16-monitor video wall. It comes across as a very interesting implementation of low-cost alternative technology to meet needs of the hardware-constrained, resource-poor but talent-rich Third World.
