It's a rotating cube colour puzzle, made in the HL2 Source engine.
Why? I accidentally destroyed mine, and realized that it should be possible to recreate it using Source's Uber-powerful entity I/O system.
I was saving it for my upcoming HL2 single player mod, but since that's ages away and this is really clever I didn't want anyone to beat me to it
There's no point to it - it's just a tech demo.
The arena is a bit rough, but that?s not the point ? it?s all about the cube!
Feel free to decompile this map and learn from it. Credit me if you make anything based on it.
