I saw these sentences but I could not understand what does "go a little crazy" mean!?
"the material can assume a lot of formats. And then you go a little crazy, and so you do various optical components or you do microprism arrays"

It's an informal way to say do something unexpected or inexplicable, from the perception that an insane person would act in irrational ways. It's usually used in a humorous context. So in this case, the author is jokingly implying that you would have to be slightly insane to choose various optical components or microprism arrays.
It's a cliche meaning "do something out of the ordinary" used by people who never do anything out of the ordinary and take offense when others do something out of the ordinary.
