So as first step I uploaded this image to Google Images, but can't find nothing similar. After all, I added  "po in the room" phrase to image search result and found this image:

This image links to [here](https://universe.byu.edu/2017/08/25/8-fun-facts-you-didnt-know-about-byu-campus/) where we can find the answer to the chal's question on second section:> **2. A giant Po the Panda statue stands in the lobby of the Talmage Building.**   >    >Computer science professor Parris Egbert was on a trip to DreamWorks Studio with a few other professors when he first saw Po’s statue in the DreamWorks lobby. After finding out the statue would be retired to a warehouse, he said his group asked for the statue to be given to BYU, where they would display it. He said DreamWorks finally agreed after multiple requests.>Egbert said he believes DreamWorks consented because of the good relationship DreamWorks has with BYU. He said many BYU alumni have gone to work for DreamWorks, including *Jason Turner, who created the data for Po’s character as modeling supervisor at DreamWorks*.
So the answer is *Jason Turner*, that turned to this flag:
