Blaqk is a collaboration between Athens-based design duo Greg Papagrigoriou and Chris Tzaferos who goes by Simek. Their street art mixes geometric forms with typographic letterforms—much of which is calligraphy. Whether black on white or white on black, on gallery walls, building façades, or abandon lots, their graphic style definitely pops. You can see much more of their work on their site.
