X-Ray Projection is a good example of what happens when tech innovation meets art. This interactive installation, called 'Out of Bounds', was created by Chris O'Shea for Designers in Residence at the Design Museum London. In short, beaming a flashlight onto the wall lets you reveal the projected image... Neat-o.
Here's a bit more about the designer: "Chris O'Shea is an artist and designer, creating interactive work for both public institutions and private companies. His focus is on developing work that encourage creative play and collaboration, challenging our perception of space and physical objects."
