I can't help but think of the classic puzzle game Tetris when I see POTO Vinclum. POTO Vinclum is an eco-friendly multipurpose building designed by Jorge Fontan.

POTO Vinclum is a series of offices, residential and commercial buildings interconnected via bridges. Gardens dot POTO Vinclum, making it a little easier on the eyes than most contemporary mixed-use buildings. No word yet on whether Fontans design will ever go from concept to reality, but I'm betting there's a good chance. The world is only going to get greener.
