mettapera build a small bar inside a table and in order to spice it up added a seven-band audio spectrum equalizer with both LCD screen and RGB leds and a smoke machine. All this is controlled by an Arduino and the bar is supported by a gas spring to help the lifting.
A neat small corner transforms in a sec to a mood changing place and the "Zorba the Greek" soundtrack helps the most. :)

Marc (uiproductions) wanted something extraordinary to wear in DC 2010 festival, after heavy thinking the result was a full-body suit of LEDs that can be controled to any color or pattern desired.
Taking a white suit and sewing up to 200 RGB leds on it and having an iPhone to control via wifi the various patterns and colors did the job.
Marc also added an accelerometer and a microphone to the suit to have even more ways to control the leds.
The result is at least eye catching and sure will make his presence noticable. :)

Sergio Vilches made a color mixer with an Arduino for some MegaBrite leds in order to control them in a more human-friendly way as he says, thus meaning determine a colour by its Hue (tone), Saturation (more or less colourful) and Value (brightness), as it is widely used in colour pickers for computer graphic programs as GIMP.
He also decided to make directly a pcb to house all that and to use only recycled components salvaged from different sources.

Alessandro Lambardi created a tool aimed at improving the piano keyboard self-teaching experience with direct interaction between the student and software (or human, remote) teacher.
The new level of interaction is reached when the student is guided on the notes to play or exercise on visually with LEDs placed directly on top of the piano keys. A Personal Computer running music-teaching software or regular score composi...
gicks87 demonstrates a paperweight made from a combination of wood and translucent epoxy resin that inside hides a led, a color sensor and an Arduino in order to read the color of paper underneath and light the led accordingly.
Simple and pretty to give as gift or enjoy it on your desk.
Code used can be found here.
Markus Ulfberg made a "mood" light controller with an Arduino to change the colors in a led strip.
He uses only one potensiometer to control all colours much like the Philips LivingColors fixture and he also has 3 modes to choose, select a color with the color selector, pulse - pulsate the selected color and random/cycle - cycle randomly through the colour palette.
Simple neat and it works, the whole details along with the code are provided here.
Kevin Darrah made 4x4x4 led cube capable of doing some prety impressive animations. In the video he gives a good explanation how the construction works by using only 12 outputs from an Atmega microcontroller.

Alieneye is a 5w LED light capable of mounting into various places and completely waterproof. The best thing is that is constructed with easy to find materials and except is sold as kit you can make your own by following the instructions provided here and a series of how-to videos found here.
Steve Hoefer made a glove that plays along with you the known game. Not only that but it learns your way of playing over time and counters your moves. Consists of a arduino, an accelerometer, flex sensors for finger bend recognition, a diy screen, some leds and of course the glove. Details of construction along with the needed info can be found here.
