Render a clip as flat-shaded geometry. The frame is laid over a mesh of triangles, and each triangle is filled with the color beneath it.
Scale, variance, and wireframe
Polygon Scale sets the triangle size. Small triangles keep the subject recognisable; large ones reduce it to a few facets. Variance breaks up the regular grid. Wireframe draws the triangle edges in light lines for a 3D-model look.
Motion
Because the mesh is fixed, moving subjects pass through it and the facets flicker between colors. Slow camera moves and soft motion give a calm, crystalline animation.
