From Music Hack Day
My hack for musichackday is an interactive musical tshirt, basically I've written a script that allows a LilyPad Arduino to use its pads as a musical keyboard. I've elongated these pads to a scale and the user can play tunes in the C scale - C,D,E,F,G,A,B,C
The piece uses e-textiles and sewable conductive thread rather than wires to conduct voltage and signal.
The user takes a stylus and plays the notes corresponding LEDs also light up.
I will write a blog post about it soon on http://rainycatz.wordpress.com
