A couple of years ago we moved into a new office space and the management decided we needed a more open cubical design. Well after many complaints about us developers not being able to concentrate due to folks walking around the office. They agreed to add some glass to the top of our cube walls (as to not block the natural light). Well, little do they know, we developers work with the blinds closed and the lights off most of the time.
Still being the picky bunch of developers we are, any distractions make us flip out. The glass helped, but we've had a lot more activity in our space with folks coming and going lately. Those little 1" to 3" gaps between the glass pretty much bug everyone, so I think I've come up with a solution, some fillers for those gaps.
Yes Brent, I've got a roll of tape to mark the door on the floor too.
