This little 3D experiment is called Metabubbles as it´s behavior and look are quite similar to those of real metaballs.

In fact it is just PV3D ViewportLayers with the blend-mode “add” that produce those gooey effects when balls with a similar z-depth pass each other – “old school”.

The cpu-load is quite high but the result is as psychedelic and relaxing as watching a lava-lamp…

Sit back and take a time out …
