In February 2010 I spend a Saturday at MadLab in Manchester. A new FabLab/ HackLab. http://madlab.org.uk/
They held a workshop to explore the use of Arduino's (mini magical computers in chips), conductive threads and LED's. I took along my crochet and enjoyed a day of talking about things I don't understand and being boggled by craft/tech possibilities!
The result of the day was these crocheted light balls. Crochet balls with LED's and watch battery's inside. Potentially the LED's could be hooked up to an Arduino and become touch sensitive, movement sensitive, sound reactive..... ooh the possibilities.
This is an ongoing project that I will add to when I have time/ learn some more technical know how.
