Extremely clever trick from designer John Leung, who’s put a coffee table with an optical grill on top of a rug patterned with a few “hashed” frames of a simple, looping animation. The net result? As you move around the room, the patterns on the rug, viewed through the table, appear to move. Dude Craft has a great “scanimation” tutorial that demonstrates how to make images of this type. [Thanks, Matt Mets!]
