Here's a couple of looping brain animations I made for Tinkercad.com
For the sponge, I used a really simple cellular displacement to rough up the surface but the main work is being done by the Scatter Volume material, which worked wonderfully for this. The twisting effect is literally just a twist modifier, with some relaxing on the verts in the middle (to stop the geometry crashing into itself) and an FFD to give it a slightly more appealing shape.
