I was experimenting with a adding surface texture to the Paraboloid Spread shader, and pushed one of the parameters further than I usually would. The result was really cool!
What’s actually happening is that I’ve added a repeating pattern to the surface of each individual mesh strip. There’s a control for the size of each texture ’tile’, and in this case, I’ve set this all the way up to 1.0. This stretches the tile image (in this case a blurry circle) to fill the whole area of the mesh, blurring it in the process. Setting the mesh blending mode to Add melds the meshes together, giving this fiery, explosion-like effect.
The fifth pic there was the result of another happy accident, when I set the tiling surface pattern for the mesh to an image input, but neglected to connect anything to it, resulting in a really nice glitchy noise-type effect, that flashes on and off in a really cool way.
