Well know Suzanne model with a varaition of the grayscott model
The King Midas had the ability to turn everything he touched into gold.
this is a relatime effect (compute shader powered) who is reproduccing this effect.
The effect is a grayscott simulation running on a mesh, using the vertex like a pixel,
and the neighbors vertex for compute a laplacian and propagate.
So no texture, no uv map, no discontinuity. you just need to have a good mesh where all vertexs are connected.
But like he use the vertex color, you need a high poly mesh for have a pretty effect.
