Trick to keep objects rotating?

I’m working on some kinetic/wind sculptures, most of those function primarily on illusion activated by the rotation. I’m wondering if there is a trick in Grasshopper for perpetual rotation, not just a slider you move back and forth, or a Turntable. A few years ago I used Bongo for some advanced gear mechanism rotations but that was convoluted and not at all parametric.

Some kind of timed loop maybe?

Nevermind, figured it out.
