So I've seen this pattern in the background and banners of websites, but I don't know what it's called. I want to see more examples, and learn how to do it myself (Using CS2).
This website has a example of what I'm talking about in it's seemless background: http://projectmgame.com/en/
I would call it a tessellation since the triangles used are regular and repeating in a unified way.
I'd call it a pattern which is the same thing as a tessellation, just not such a "fancy" word.
Just because it happens to be a pattern/tessellation of triangles, that does not give it a specific name.
