is it art?

In class we looked at a bunch of examples of different types of "art", food art, anime, outsider art, etc. I asked you to examine it and tell me if you thought it was art according to some criteria I gave you. Now I want you to look at something else and tell me if it is art. I found this website last year and just thought it was one of the coolest things I have seen, but is it art? I also found this today. Could it be art? Take a look and comment to let me know.
