Cafe Art

A mind boggling magic trick. Can you figure it out?

The former book editor whose fascination with one material has gone to artistic extremes.

This amazing sculpture is made out of 714 metal balls which move under the command of a combination of codes, electronics and mechanics. This kinetic sculpture needs a surface of six square meters in order to function properly. The 714 aluminum balls are individually controlled by a computer stepper-motor, and they are hung with very thin steel wires which have a diameter of under 0.2 millimeters.

Artist and TED Fellow Aparna Rao re-imagines the familiar in surprising, often humorous ways. With her collaborator Soren Pors, Rao creates high-tech art installations -- a typewriter that sends emails, a camera that tracks you through the room only to make you invisible on screen -- that put a playful spin on ordinary objects and interactions.

Keith Barry shows us how our brains can fool our bodies -- in a trick that works via podcast too. Then he involves the audience in some jaw-dropping (and even a bit dangerous) feats of brain magic.

The suits, numbers and colors in a deck of cards correspond to the seasons, moon cycles and calendar. Marco Tempest straps on augmented reality goggles and does a card trick like you've never seen before, weaving a lyrical tale as he deals. (This version fixes a glitch in the original performance, but is otherwise exactly as seen live by the TEDGlobal audience, including the dazzling augmented reality effects.)

This guy was hanging out in Yoyogi park in Harajuku, Tokyo, on a Sunday afternoon. He has clearly practiced a lot! I loved the music he played during his performance. My friends and I were completely mesmerized. He has a very expressive face too, with a charming smile... it really sells the show in the end. Made me feel like a little kid.
