Okay. I studied the rules. I studied the photos. I took a break. I studied the photos again. I found 8 distinct, yet subtle, differences in the two photos. (Yes, it has been a slow day at work.) At the risk of allowing history to repeat itself and giving away answers to others in the case that I missed something (which I doubt as I found eight things that ARE different), here is what I found:
1.) Near the back corner of the room there is a red pen/marker lying on the floor. It appears to have been rotated roughly 30-40 degrees clockwise.
2.) On the middle left of the picture is what looks like the red handle of a pair of pliers (only one side of the pliers can be seen). These have been flipped over.
3.) Between the pliers and the pen is a small pile of screws. These have been moved to the left (and the pile is slightly more compact).
4.) In the middle of the picture is the red Jig saw. The white plug of the extension cord that it is plugged into has been moved to the right roughly six inches.
5.) Roughly to the 11 O'clock position of the pile of wood is a black triangle (screening, sand paper, not quite sure what it is) that has been rotated roughly 90 degrees counter clockwise and slightly away from the pile.
6.) Near the back corner of the room is what looks like a white light box. In front of that, is a board with a white thing on it (not sure if it is paper, plaster cloth or foam, but the whole board that it is sitting on (white thing included) has been rotated about 200 degrees clockwise.
6.5) There is a black thing on this board as well in the first photo that cannot be seen in the second.
7.) At the bottom of the photo is the dust buster with two boards sitting on the handle. In the second photo, these boards have been moved off of the dust buster.
8.) Now, this one is really tricky. If you look at the first photo and find the red pen mentioned in #1, and you follow the line of the pen to the wood pile, you will cross a small smudge on the floor. Lint, deconstruction debris... not quite sure. If you look at the second photo, this thing is lying parallel in line with the top and bottom borders of the photo. In the first photo it sits at an angle to that parallel line. As far as I can tell, the camera is in the same position in both photos and nothing else has changed it's perspective, thus it is a change. Small, subtle, but a difference.
How'd I do?
