Is it possible to make a blob like object like in locoroco?

I tried this a long time ago and didn't have much luck. But there have been some new features added since then that might help so I think I might give it another shot.

The basic idea behind it would be to link several physics objects together with hinges/springs in order to form a blob mesh in such a way that it won't collapse on itself. You can see the general theory on blob construction here:

So I'd basically make little ball things, then attach them together with hinges?

I think spring force is the way to go on this.

There's a couple people in chat right now trying to figure it out. Well, me mainly. But some others are looking at it too.

Quazi was the guy who made the orange-shooting-jelly thing right?

Quaziblobs are made by Quazi.

This thread is not about Quaziblobs :P. It's about Loco Roco style blobs that move and deform with physics.

I got close last night but I have a feeling I'm not using physics spring force correctly. David has a Tower of Goo example that shows spring force in action, and the structures are pretty sound. But my blob loses cohesion very quickly.

If you run it the nodes just spaz out all over the place. If you bump up the mass on the nodes to 200 or more, they stick together better, but a mass of 200 is much too high for the springs to support the weight and the blob sags into a pile of mush. But at least then you can see they are connected properly.

ive done this with springs, and sprite distortion.
