Finally, this package arrived yesterday in my office:
I was able to try out an Oculus Rift before a few times, but now I have my own. I only tried the demos before, so I never wrote any actual code for it, but skipping shortly through the documentation, it doesn't seem to be difficult. The next days, I'm going to try to figure out if and how support for the Oculus Rift device will make sense in CopperCube. Because, yes, it would be great to create 3D apps for that device with just a few clicks. :)
