I came across this nifty concept for an electronic plaything earlier this week and thought I’d share it with you guys.

Steve Gilbertson’s interactive color cube uses a 3-axis accelerometer to detect movements and relays that information to a grid of brightly colored LEDs to create a portable light show in a box…

This huge LED screen displays mesmerizing patterns of light and video to passersby. But the really amazing thing about the enormous wall of light is that it’s completely self-sustaining. That is, the light panels themselves harness the energy of the sun during the day to power a colorful light show at night…

Inspired by the mind-bending transportation technology in last year’s sleeper hit game Portal, this video clip uses digital augmented reality technology to produce a similar effect in the real world.

Created by EmmanuelMFr of France’s Total Immersion, the illusions in the video really are reminiscent of those in the game…

This interactive art display takes data it collects on passing traffic and displays moving images which react to vehicles as they drive by…

Instead of using a traditional 2-dimensional display surface, Shade Pixel renders information using a deformable skin surface which provides a 3-dimensional texture to its output…

Here’s some pretty cool news which could provide entirely new ways to interact with your computer or game console. This new technology will enable automated 3-dimensional tracking of heads and faces using a webcam along with some very special tracking software…

With all the buzz about the new iPhone SDK, all kinds of nifty applications are starting to crawl out of the woodwork. Of all the coming programs, this LEGO construction concept application has to be one of my favorites…

This unconventional design tool provides a unique way to create new typefaces. Working somewhat like an analog music synthesizer, knobs and button pushes influence the shape of your font characters…

Most robots are controlled using a joystick or other traditional input device, but this new system allows operators to issue commands to robots using simple hand and body gestures…

This incredible art installation records the tiniest human breathing patterns and magnifies them into a room-filling blast of wind.

Created by interactive artist Scott Snibbe, Blow Up is comprised of two main pieces. On one side of the room is an array of 12 small impellers which act as a breath-controlled input device…

This might look like a curtain of randomly assorted lighting fixtures. But it’s actually an interactive video display that can detect movements of passersby and mimic them using light.

Entitled Space Invaders 2008, the light installation uses a grid of 176 unique lighting fixtures to work its magic…

Sure, there are lots of devices which are starting to embed motion sensors or touch screens to power new user interface paradigms. But this is the first time I’ve seen a motion-sensitive device which is designed to be operated entirely with one hand…

As much as I love my iPhone, I can’t stand getting fingerprints all over the phone’s beautiful glossy screen. So I was jazzed when the guys over at Norway’s Elliptic Labs let me know about their new touchless user interface technology…

Why dig through stacks and stacks of individual comic books when you can quickly find the exact one you’re looking for using a wall-sized über-cool Minority Report-like user interface?..

This music sequencer takes the same basic interface concept as the ball bearing sequencer I recently showed you, and makes it deliciously chewable. Instead of shiny metal spheres, this sequencer uses a bunch of colorful candy-coated gumballs to make a beat you can dance to…
