2 weeks ago my coworkers and I celebrated our manager's birthday in style. The big event was when we all showed up in his office dressed like him (white polos, khaki shorts, socks and sandals, and bald caps) and ate cake! Here's a picture of all of us (Jensen, our manager, is the tallest guy in the back.)
Clay and I also created a wall of post it note art. The final product used 726 postit notes (in 8 different colors) and was 5'6" wide and 8'3" tall. It took about 2 hours to design and 3 hours (plus another hour of goofing off) to assemble.
If you can't tell what it is, it helps to go to the end of the hallway.
If that doesn't help, looking at it next to the orignal picture prolly will.
