Art can take several forms. In fact, everything in life is art. Here, from foreground to background, are painted cows from the (as you already know) Cow Parade, the pyramid which domes (hhmmm...can a pyramid dome?...anyway...) the Metro station of Panepistimio and, finally, the main building of Athens University where, between the columns, the Sciences from the previous post are barely visible.
Every basic geometrical shape is here, it seems everything fell into place.
