I started thin Thinking about this all over again lately now that all the easy to mod minecraft clones are popping up, voxel.js or python minecraft in 500 lines for examples. In a minecraft environment it would look a bit less like a employee playing a game and the possibilities are really helpful if you think about them, virtual server rooms you can actually walk into, punch a rack and get a menu, actually punch a connection to take a node offline. Wouldn't mind a way to physically see memory and cpu usage of processes mapped to the size or color of objects in this type of environment either.
You could certainly do some interesting 3D 'dashboards' once VR gets cheap enough, would be cool to look out over a grid of boxes where size was related to memory load and color temperature.
Not sure it's practical in that it's damn hard to beat the informational density of good 2D graphs and text but it would certainly be cool (which is often the best reason to do something).
