"It's a bit of hacking and a bit of stitching."

I dipped in to see some of the fascinating stuff at the craft session, where we were told that the crossover between technology and fashion is thriving.

Just a couple of examples: Diana Eng's heartbeat hoodie which takes photos when you heart rate rises. She said she was trying to tweak the algorithm so that rather than take pictures when you run down the street, it would take pictures when you meet someone you're attracted to.

Syuzi Pakhchyan's ariel brooch was rather charming. It is light-sensitive, so tweets quietly when it is in strong daylight.

One problem with many of these products though: washability. Unless they could design clothes that clean themselves?
