like you see, it is currently in alpha-phase. but if you want to use it at the moment, you can download greenfoot 3d at http://metropy.net/greenfoot/3d/greenfoot.jar It can replace your greenfoot.jar (Windows: C:\Program Files\Greenfoot\lib\extensions). Dont worry, it supports the normal Actors too, so you can run your existing greenfoot projects like before. Lizense and source code, see http://metropy.net/greenfoot/3d/greenfoot.zip

Yea, ok; everyone who want to know some of my code; feel free to contact me at GreenHouse@metropy.net Also for the other scenarios i created.

@erdelf: Thanks :D @FlyingRabidUnicornPig: 'view page source' will show you the code of the website; in my case the 'special' code is created at runtime by the Scenario-Applet.. :)
