Hi, Sorry if that was mentioned on the forum (or may be implemented in software) but I just started using SF and I cannot find something what I thought it should be there for sure. What I'd like to achieve is to use one picture (just one) that will be constantly moved / animated. In "Options" there ...

The term illusory motion, also known as motion illusion, is an optical illusion in which a static image appears to be moving due to the cognitive effects of interacting color contrasts, object shapes, and position.
