I know this is like saying "I could do what Jackson Pollock does if I just threw some paint around"...but I can't really shake the feeling that that Muuto Post looks like something out of my dorm room but for 1255 dollars.

I guess the modularity (you can purchase more lights) is a real feature though?

I'll note that many of the glass blocks they use are available all over, for a few dollars. I bought a few Doric glass blocks, stuck some diffused LED strips below them, and printed a stand/enclosure, all for under $15. Good gift for friends.
