The World Largest 3D LED Display
The “Electrotechnische Vereeniging”, the association for students of electrical engineering from the Delft University of Technology (TU Delft), will reveal the world’s largest 3D-display Sunday 23rd of April. The display measures 8 metres in width, 4 metres in height and 2 metres in depth and consists of a matrix of 8.000 LEDs with table tennis balls around them. This stunt is being organised because of the celebration of the 100th anniversary of the “Electrotechnische Vereeniging” (ETV). The display will be revealed on Sunday at 9.00 pm local time on the ‘Markt’ in Delft.
It will be possible to send text messages to the MatriXX during the times it is operating. Send your sms/text to +31 (0) 6 24 171 797 . It will be displayed during the next sms display time slot. Threats, rude language etc will be filtered.

The Cubatron - LED PingPong 3D Display
The Cubatron is the world’s largest true 3D color graphics display (until the BRC is built in August 2006). It is 8×8x8 feet in size. It consists of 729 voxels (3D pixels) arranged in a 9×9x9 matrix, spaced 10 inches apart from each other. Each voxel is a 40mm diameter ball that can be independently set to display a 21-bit RGB color. The entire display can be updated about 30 times per second. The voxels “float” in space so that the viewer can see through the cube and have a view of most of the voxels from any position.
There are 729 voxels. Each one has a microcontroller on it. There are 27 strings of 27 voxels. The voxels on each string have an address of 1 through 27. They are sent commands using a special synchronous protocol which consists of a frame which contains RGB data for each of the 27 voxels on the string. A frame is sent on every string about 30 times per second. The voxels take the last RGB value they got and PWM the RGB LED to display the proper color.
A PC running FreeBSD generates the patterns to display. The PC converts the RGB data into the 27 streams of data to be sent to each string of voxels. It sends this data across an ethernet connection to an ethernet printer server. The printer server’s parallel port outputs data to the voxel driver board. The voxel driver board has a PIC18F452 which demuxes the incoming data and sends it out to the 27 voxel strings while maintaining proper timing for the synchronous protocol. The Cubatron requires 100K bytes of data per second.

BION - between non-living and living matter
“Bion” is an interactive installation that explores the relationship between humans and artificial life. “Bion” makes reference to an individual element of primordial biological energy identified as orgone by the scientist Wilhelm Reich.The installation is composed of hundreds of mass-produced, 3-dimensional glowing and chirping sculptural forms. Each bion, measuring approximately 4×3x2 ½ inches is an synthetic “life-form” fitted with an audio speaker, blue lights (LED’s), and multiple sensors. The bions are suspended by fine gage wire connected to panels that are attached to the ceiling. When installed the panels form clusters of bions arranged at different elevations. Each bion has the ability to communicate with the others and with viewers that enter the space.
When a viewer approaches the installation space she will witness a dynamic array of blips of sound and blue light emanating in cloud like patterns from all parts of the room. She notices that the source of the light and sound come from hundreds of small organic shaped forms called bions . The bions are communicating, unaware of the approaching visitor.

360° LED Display
The “360° LED Display” is equipped with thousands of bright LEDs. Each of it spins around a drum to create vivid image in a 360-degree panorama.
Using patented technology, the LEDs component counts are reduced to several tenths of that in conventional LED displays. It utilizes fewer LEDs, and consumes less operation power. Maintenance fee is saved to a great extent as the result. Yet, the “360° LED Display” incredibly shows far excellent performance at VGA, XVGA, VHS and SVHS.
Unlike conventional display which has red, blue and green color elements separated, the “360° LED Display”‘ flying red green and blue LEDs are turned on right at the same spot to create an effective pixel which makes the image perfectly crispy.
The “360° LED Display”’s real pixel has a size as fine as 2.5 by 2.5mm. Crisp and vivid images remain for any viewing distance and guarantee authentic video quality even for spectators close to the display.
All flying LEDs are calibrated using proprietary correction technology to assure color uniformity across the entire screen and display 16.7 million distinct true colors.

3D Display Cube
The 3D Display Cube encourages the viewer to think about the limitations of current display systems and the representation of spatial data. To be able to recreate spatial data will allow us to display ideas closer to the way we envision and experience them; with depth. The 3D Display Cube was hand built and constructed from one thousand individually controllable LEDs soldered into a 10×10x10 freestanding matrix.
Each LED acts as one spatial pixel and can be refreshed at a rate of over 60 fps creating a low resolution 3D television. The Cube has an input device (serial input) that allows data to be sent to the cube to manipulate the 3D data live. The display unit can then be hooked up to a camera for live video input , or to a sound module chip to take in live audio input.
