Transform is made up of over 1,000 plastic rods attached to individual motors. When someone passes their hand over the table top, sensors detect the movement and cause the surface to ripple like a wave.
"It's a completely new form of physical and digital computational material," says Ishii, who spoke to us at the Lexus Design Amazing exhibition in Milan last month, where the project was on show. "This is equivalent to the invention of a new medium like painting, music, plastic or computer graphics."
Transform was created by Daniel Leithinger and Sean Follmer of MIT Media Lab's Tangible Media Group, overseen by Ishii, and is part of the group's Radical Atoms project, which explores physical manifestations of digital information.
"Pixels are intangible," Ishii says. "You can only use them by being mediated through remote control, like a mouse or a touchscreen. We decided to physically embody computation and information. We're coupling physical materials with underlying computation."
As well as reacting to people's movement, Transform can be programmed to represent 3D images and animations, just like a digital screen. But Ishii believes the possibilities of this new "computational material" are limitless.
"When movies were invented there was no content, no good applications," he says. "But now it has blossomed in a very interesting way. So think about Transform as a new medium with infinite possibilities."
He continues: "This is a challenge to all creatives and artists - what will you do with this? We present these new possibilities, which no-one ever imagined. Now people have to think, create and respond. Digital is not the end; there's something beyond that."
