Fluid
A stirred fluid simulation that paints the frame and drags the layers below it
This is an actual fluid simulation — the same solver behind those cursor-ink demos — running live under your stack. A stroke pushes velocity into a grid; the solver then works out where every bit of that flow has to go so the fluid doesn't compress, which is the step that turns a smear into a swirl: push here and an eddy opens next to it. The layers below get carried along that flow rather than nudged off their spot, so a shape stretches into a ribbon that curls back on itself, and the ink it drags along keeps folding into finer and finer filaments. It has memory — the frame you see is built on every frame before it — so unlike the rest of the stack it can't be made to loop seamlessly.
I. Made with Fluid
II. Everything else
- Blinds — Displace the image into banded slats — linear, radial or tiled
- Bulge — Swells the layers below outward from a point, or squeezes them in
- Cloth — Hangs the layers below like fabric in the wind — a flag, a banner, a curtain
- Cylinder — Wraps the layers below around a turning drum, with repeats and shading
- Droste — Nests the layers below inside themselves forever, and zooms through them
- Echo — Repeats the layers below as a stepped run of hard-edged copies
- Envelope — Fits the layers below into a band with a bent top and bottom — type on a slope
- Glass Shatter — Breaks the layers below into shards of glass that catch the light
- Kaleidoscope — Mirrors the layers below into slices that meet at a point
- Lens Distort — Fisheye / pincushion lens warp with zoom and chromatic fringing
- Mouse Trail — Displaces the layers below along a fading trail of the cursor
- Noise Warp — Liquid noise displacement of the layers below
- Reflective Floor — Mirrors the layers below onto a glossy floor under a horizon line
- Smudge — Drags the layers below through a viscous current, like paint pushed while wet
- Tile — Repeat the layers below across a grid
- Twirl — Twists the layers below into a spiral around a point
