Back when I worked for Frontier/Global Crossing, my cow orkers who had window offices often used them as whiteboards. That impressed me as such a good idea that when I went to SunGard and had a window office, I started doing the same thing myself.
Today, I needed to hash out some big diagrams, transaction diagrams and XML with a couple of other guys, and since none of us had very big whiteboards in our office, I suggested we use the windows in the break room. The people I was meeting with didn’t believe me at first, but went along with it once I demostrated that it wipes off as easily as on a whiteboard. But everybody who came into the break room while we were at work stared in disbelief and made sarcastic remarks.
Is using a window as a whiteboard really that unusual?
