We present a new compiz plugin to use multiple projectors, in order to obtain a very high resolution desktop (with two HD projectors, the desktop is typically 3800×1000). The most important feature is that projectors alignment is done manually (very quickly) and the edge blending is computed automatically. The result is a perfectly aligned, anti-aliased and edge-blended desktop.
