A quick, rough implementation of an idea I had for implementing GPU accelerated metaballs.

At the bottom are planes with a white blob on them, additive blended. These are the points.

Then there's a plane over them with a material that takes the destcolour and uses it to scroll a texture with the colour gradient on it.

Simple!

Anyone got other ideas?
