Cue in interior designer Kelley Moore, who approaches the bane of all workers with an optimistic guide to cubicle decor inspiration, Cube Chic: Take Your Office Space from Drab to Fab! Hip-Hop, a pub, safari, cubism, a garden, and cabin style decor are all presented as inspiration, showing those three walls keeping you caged in for the day can be less San Quentin snore and more Elle Decor. Personally, what I'd really want is the secret built-in sleeping nook under my desk, complete with alarm clock stand, à la George Costanza.
I once worked in a law firm as a clerk before going to grad school. The work was very easy - I often accomplished 95% of my daily tasks within the first 1-2 hours of the day. That left the remainder of the day to surf the internet, shop catalogs, send interoffice IM's to the other non-attorney staff, make multiple trips to the caf for free fountain drinks (and consequently frequent trips to the loo) all while attempting to appear "busy". After a few months, I realized that since my cubicle was open to the corridor but backed by a large wall, I could go under my desk and nobody would see me. Ahhh, finally I was able to take afternoon naps.
It was the best job ever.
When my husband was offered an office, (a big deal for most Manhattan office workers), he declined because his cubicle functioned so well. He was pressed to take the office and finally relented, but insisted on moving the cubicle in with him. It actually does offer more usable space -vertical and horizontal- than those with the requisite credenzas, etc. It's also very funny looking in there.
This is a nice idea but many offices (mine for instance) actually won't allow such decoration as they want to keep a uniform look.
