Magnificent Date Stamp Artwork

That's not a photograph or a painting you're looking at. It's actually made using something many people have sitting in their office - a normal date stamp. Berlin-based artist Federico Pietrella layers ink dates to create the gradients desired for the scene so that when viewed from a distance, they all blend together, revealing an impressive portrait or city scene. The longer I stare at each one, the more amazed I am at the patience and skill that went into creating these mind-blowing works.
