Based on everything seen, the contest could be renamed to "Pizza Parody"  

Honestly, I had a lot of fun looking at all the creations that were submitted for this contest. I don't know what's more twisted, pizza that looks like a salad or cooking pizza in a pot. What seems universal to most of the participants, is whatever they make as a base, it's enough to sprinkle tomato over it and voila... it's pizza. The strange thing is, someone took a picture of a pizza bought in a restaurant, even the professionally made one looks very little like a pizza.
I'm not sure I saw one or two that I might want to try eating.

At the beginning of the contest, fillippone warned about the possible abuse of AI, MidJourney for example really gave very good images of food, that's correct. At least we can be sure here, AI is certainly not used, it just doesn't have this much creativity as shown by many in this contest.
