Spencer and Diana graciously helped us set it up, so here's a picture of the tired team (plus Spencer haha) when we were finished.
Day 1: When we came back to observe the next day, two of the tiles had already ripped up, but we left them as they were so it wouldn't skew the pattern, and observed people for a couple hours.
Hyung-Min set up his camera to his laptop remotely so he could take sneaky pictures and video around the corner and watch from his laptop screen.
Day 2: The tile formation ended up more complex than we had thought. In theory, each color would just cross to reach the opposite side of the hallway by the end, but in the middle they all ended up crossing and it got a little crazy. We had also gone out and bought a new kind of tape - good old duct tape - since the packaging tape hadn't worked out.
Here's the team partway into setting it up.
And finished!
Yeah. It was a good thing we switched out the tape, because today (Day 2 observation) it rained pretty hard most of the day, but the new tiles still held up 8) They not only stick much better, but also look nicer in the way they frame the tiles, and are more noticeable as well. Why did we ever question duct tape?
On to Day 3! I'll make another post with more pictures and all of our observations for all four days along with our notes.
