In his last Motion tutorial of 2020, Simon Ubsdell experiments with an oscillating emitter.
If you need an indicator to show you how flexible Apple's Motion can be, take a look a this new tutorial from Simon Ubsdell. He very cleverly uses an emitter moving in harmonic motion to build Lissajous curves on a floor.
It is quite amazing that Motion gives you the tools to build something that complex in 3D.
Great stuff from Simon, you might want to subscribe to his Patreon page for more advanced tutorials in the future.
