The Arduino-controlled "Rainbow Jar" lighting artwork

Although projects based around an Arduino and RGB LEDs are considered quite common, there's still plenty of potential to create all sorts of interesting and artistic designs with the use of some work and imagination. Recently an interesting and compact example of this came to our attention - the "Rainbow Jar" by Instructables user "phenoptix". They've inserted the Arduino, power and an addressable RGB LED strip inside a jar, and filled it with RGB LEDs for an ironic effect as you can see below:

The use of the jar is an inexpensive method of getting a sensible enclosure that looks good and is easy to work with. To learn more and for how make your own, visit the project Instructable. And for more, we're on twitter and Google+, so follow us for news and product updates as well. 

If you're looking to make more creative designs with LEDs, consider the Freetronics RGBLED: full colour module. It includes a bright RGB LED on the top of the board and a WS2801 constant-current, addressable, multi-channel LED driver on the back. This smart module can be daisy-chained, so you can connect a number of these together in a string and drive each of the module colours individually from your microcontroller.
