Raspberry Pi Breathing LED
This is a demonstration of using Ruby and the WiringPi Gem to pulse an LED connected to a GPIO pin in a manner similar to the sleep indicator on a MacBook.
A video of the effect can be found here: http://www.youtube.com/watch?v=NCUMXK7qf-c

I'm just starting with ruby and the pi. but i made a site: rubinio.org. If you would be willing to write your project experiance in a short article, that would be great. torsten@villataika.fi
