The Wobbulator enables laser graphics projectors to project lumia, diffraction, and scan-through effects. This is a bolt-on device that attaches to the front of your projector, just in front of the aperture.

First used in the hit horror movie Hereditary, the WobbulatorTM dramatically broadens the effects possible from your galvo-based laser. The hallway scene in Hereditary was done as a scan-through effect, the WobbulatorTM supplying a wobble to the eerie shape projected moving up and down the hall.
