I am currently editing a new VEX Quicky where I look at polar coordinates. In addition to that video I built in the mechanic into the asset.
That option allows to create some cool shapes with interesting animations. This is already implemented but before I hand it over to you guys in the 2nd tier - I wanted to add some parameters to another system that basicly an evolution of this.
And that is a version of the Tron-like rings. When this one is also a bit more fleshed out I share the next version with you.
