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.
so cool 
great work fella!!
You da man! I would love to shadow you for a week.
Well done ! as usual !!
the sponge brain is ace, great work.
Thanks all!
If anyone’s interested, here’s a viewport preview of the sponge mesh twisting. It’s certainly not perfect, but it did the job!

Thank Bobby - although I would definitely spend that week showing you superhero movies 
brain sponge is very convincing - thanks for sharing that!
I love your work on account of it being so far removed from what I do on a day-to-day basis. Always refreshing to see, and always very creative.
