Modifying a hat.
Personifying mass production.
Hand-made: sewing and soldering and programming.
DIY: well, I didn't make the LED's nor the chip, nor the pieces of cloth, the batteries, the rest, yes..
Recycling discarded LED's, the red ones, not very bright, i always recycle parts....
Bling: adding some bright LED's and two hand shapes made with a lasercutter.
Yes and no:
yes because of the different things you have to do: sewing, programming, soldering all a bit from incompatible domains.
no: this is not String Theory, it is rather normal stuff on all levels.
YES: this is an invitation to make your own versions and explore further, you can add all the things from your bag of tricks!
These few very bad shots to prove that it works. Filming LED's is somehow difficult business with my cheap digital camera :-)
