A robot blinks its antenna and scans with a glowing eye.
This scene is a keyframed frame animation rather than a live rule: each frame is painted into the timeline, so the loop is exact and repeatable. Phluxel does both — rules that simulate, and timelines that play back what you painted — and you can stack a rule on top of a timeline to add fire or rain over painted motion.
Phluxel runs in the browser as a demo, and the free desktop edition has every feature with a watermark on exports.
