Coming up with the clues for the event was sort of a difficult process. I had to find ways to connect various existing images in ways that wouldn't be too obvious to the participants. For some, it was a matter of slightly altering an image (like replacing a black cat with a white rabbit, while allowing the caption to still talk about the fat black cat), and others simply had captions that related to one another. Chris worked with me on the captions for many of the images, especially the ones that weren't a part of the clue chains. They served as a way to sort of throw participants off and made it so that the clued images weren't too obvious to spot. Zoe came up with the script that we used for the images, which whispered the image's caption to the participants when they touched the images.

(in this case, there was never a cat, but the caption said there was for the purpose of our event.)
After the event started, it was evident that the way the clues were set up wasn't as clear to the participants as they should have been. Some thought that all the clues were inter-connected and led to a final piece of evidence. It was intended to be 3 different clues with their own, separate, chains leading to 3 different answers that would fit together to point out who the thief was.
During the class event, it became apparent that the clues might have been a bit difficult to decipher. I didn't want to make it too difficult to solve the case, but I also didn't want make it too easy for everyone. In the end, I thought it would have been better off having the puzzle be too difficult and occupying our allotted time slot, than being too easy and ending up with a lot of people with nothing to do.
