Great work! How do you maintain the blob shapes? I usually use springs going outwards from the centre...

I use pressure which is calculated by taking the difference of the current area and target area of a blob. The points forming the blob are pushed in the direction of the surface normal based on the pressure.

Very interesting Reminds me of quadtrees, how the smaller sections don't exist until other objects are nearby

It's a bit simpler structure that I'm using called Spatial Hashing.

The specific squishy feeling makes way more sense now that you can see how the shapes sort of roll. You can't see the rolling without the debug markings.

There is a simple implementation to simulate friction which makes the blobs roll instead of sliding

You could pretty easily turn this into a fun mini-game with a few more steps! Introduce a set of colors and make it so that making similar colored balls touch makes them vanish and add to a score counter! If the space fills you lose

The video is so extremely compressed, I only see the colors red and black.

Yeah, I know. Twitter is bad at compressing videos. If you watch it long enough it might load a higher quality version.

Beautiful! I want to use a similar approach for data viz
