Also, the last version of Croquet - we refer to it is C5, was originally built on Lively Kernel.

"The Colony" on Github!

I finally did it. The Colony was the first realtime 3D adventure/shooter - 1987. I posted the entire source code for Mac, PC and Amiga on Github.

My namesake project. A great overview from The Register. Unity+Croquet is awesome.

Demonstration of a hillside world where even the grass is synchronized with the wind on every users machines. We then generate thousands of NPCs (non-player characters) with simple AIs that also act and react perfectly replicated with the world. Up to 5000 NPCs can be generated in this scene with minimal overhead.

This is perfect. Both simple and true.
