Spinning parts and a pulsing light

Spin speed turns a part on its own, and two stars spinning against each other read as a light that pulses.

What you see

A gear that turns and a lantern that pulses. Neither fires anything, and neither costs a barrel: they are plain parts with Spin speed set.

The trick

A spinning gear and a lantern of two shapes turning opposite waysSpin speed:turns forevertwo shapes spinopposite ways:it pulses

Spin speed on a part is rotation per tick, 25 ticks a second: 0.05 is about one turn every five seconds, 0.5 is the slider's end. The editor's preview does not animate, so you only see it in play.

The pulse is a discovery a skill user sent in: put two star parts on the same spot, a bigger darker one under a smaller lighter one of the same hue, and give them equal and opposite Spin speed. When their spokes line up they look like one bright star; half a spoke later they interleave into a dimmer, rounder blob. The eye reads it as a light beating.

Numbers that matter

SpokesSpin speedBeat
3±0.05about once a second: a lantern, a heartbeat
3±0.12a flicker
6±0.05twice a second

Beat period in seconds is (360° ÷ spokes) ÷ (2 × spin × 25 × 57.3). Three or six spokes read as light; four looks mechanical.
