Because there are no instructions at all about what will happen when you click, I almost immediately created a "transporter accident" where I spawned in a new shape that intersected with an existing shape. They became locked together, and this new compound shape seems to exist as some kind of physics engine edge case. It struggled madly to find a low-energy state, rolling and jittering around, sometimes seeming to almost stop, and then gain energy again from nowhere and start moving again.

I made something that looked like someone in a body bag just woke up and were trying to frantically find their way out. Not gonna lie it wasn't not a little disturbing...

Yeah. I fast clicked quite a train, and its now shuddering and scootching from fear or ecstasy. Its hard to tell.

EDIT: If you click in place at the bottom you can create some interesting "solids". And after a few they start fighting it out.

EDIT: A cool effect is to make a "solid" with one or more open shapes attached. They go springy spinner ballistic berserk.

When you fill up the space in 2D & wireframe modes, their rad moves look like living geometrica bacteriosa. In 3D & wireframe they look like they are ... well, doing things.

Also, you can hang them from the roof. Give them legs and arms.

If you create a couple layers of loosly connected shapes across the bottom, it acts like a powered trampoline.

Way too fun. This needs to be the next big casual gaming brand after Angry Birds. I want to solve problems with them. Shoot at them. Shoot them. A two-player shoot out would be hilarious. Definitely drop things on them.

You can also anchor elements to the inside of the frame,

& drop them outside the frame.

Wow, didn't expect to see my implementation here :)

Bit twitchy indeed but still fun. Instantly took me back to "rubber glenz vectors" in classic Amiga prods[1]

What's the physics solver used here? This demonstration quickly runs into common problems associated with overly simplistic solvers/integrators where everything starts to become unstable and "vibrate" / "twitch".

It's nape-js

While the gummy geometry one is a little twitchy, but most all the other demos were very stable, much more than most other 2d solvers I've seen.

It seems to be broken on Firefox. It shows 3/8 players, the circles are flickering madly and I can't drag them.

Yeah, fixing that demo is on my TODO list, but for example, I've implemented it a bit better here: https://newkrok.com/gamer-zone/project-throttle”

that is completly mad fun very silly looking stuff decidedly biological with enough elements

edit:it's ALIVE! and evolving!

Too much fun.

Feels pretty right.
