Here’s an awesome bit of high tech urban mischief. Greg Petchkovsky uses 3D photoscan software and a 3D printer to create objects that blend seamlessly into their surroundings. A solid brick appears to be melting, the corner of a sandstone block has worn away to reveal that it’s made of LEGO bricks. Made for the "Make it real" challenge on Instructables, the pieces are wonderfully convincing.
Watch this short video, entitled Mixing Digital Sculpture with Real Objects, to see how Greg creates these subtle works of playful street art.
