Claim:
1. A method comprising: providing two or more projection systems, each of the two or more projection system comprising a reflective surface and a controller to oscillate the reflective surface about an axis via an activation signal comprising an AC voltage amplitude; arranging the two or more projection systems to each project an image on a display surface; sending a control signal to the controller of a first one of the two or more projection system to off-set the activation signal to cause the controller to off-set the oscillation of the reflective surface within the first one of the two or more projection systems relative to the reflective surface in a second one of the two or more projection systems such that the image projected by each of the two or more projection systems are in co-operation on the display surface, the control signal comprising a DC voltage amplitude.
