I did something like that for a middle school project like this, only we had to build a pyramid... so I made one out of solid krackle and Hersey bars with royal icing to "cement" them together. It stood a good foot and a half tall.... yeah i tended to go all out on projects in middle school.
Reddit revolves around finding cool stuff from other places and posting it. Not giving credit is frowned upon, certainly. dART is all about original content, so stealing something from Reddit is a heftier crime, I'd say. It's not art, and this person didn't make it.
