Abstract:
1. A method, comprising: using a microprocessor for determining a velocity of points of a gobo; using the microprocessor for defining slices of time, based on said velocity, at which different image-processed gobo images are to be displayed, using the microprocessor for carrying out an operation on the gobo image to change a shape of the gobo being displayed based on said gobo images between a first shape and a second image-processed shape to provide modified gobo image representing a shape and color for the gobo; using the modified gobo image indicative of the current gobo image to display a colored light shape; at a time related to said slices of time, automatically determining a new image with a new gobo shape that is one slice closer to the second image-processed shape, and using the new gobo shape to display a new colored light gobo shape.
