One time when I was working at a radio station in Australia, my managers assistant decided to cover his cubicle in plastic wrap, even across the top! He cut out little windows and even a door. But it certainly wasn't as artistic as what this guy has done!
A new employee asked his boss if he could decorate his cubicle, and he got the okay, so he went all out. He turned it into a faux cabin . . . with wood panelling, a fake fireplace, and a decal of a window with a view of the lake.
Check it out here, absolutely brilliant! I wonder how long this took?
