Trying to understand the various gobo dmx toys (have no experience with gobos at all). Could someone please explain differences, pros/cons between effects that can be produced with gobo rotators (e.g. Apollo Smart Move) vs. an animator (e.g. Rosco Infinity). Others? Any advice for getting feet wet with gobos (fixed and rotating)? As we don't have permanent facility, and have to rent, I unfortunately have limited ability to experiment in real life... Thanks.
