RTS Games?

I was thinking more like "have you any idea what it would be like to do modelling with that thing"? Compared to current GUI's of any given modeling program, that would - and will - be a serious improvement. Well, I only have experience of Blender (good but complex - I haven't learned it yet), Truespace 3.2 (*family forum self-censorship*) and X-Plane's Plane Maker program (basically good, but terrible screw-ups like
complete lack of undo/redo function and terribly error-prone editing are not a good combo), but I don't expect any other modelling programs to be remarkably better in terms of user friendliness...
Same applies obviously to graphics applications. Heck, anything. I want to make myself one of those.
BTW, what was that operating system in the computer he displayed the thing with?
