Oddly enough, I'm the one in the house that sews. My wife thought I was
crazy when I drew up the designs and ordered the parts for a tutu with LEDs
embedded in it for my 3 year old niece. What's better than a chance to play
with some wearable technology *and* win best uncle ever?

I think one of these nights I'll bring her to an open hack night, so she
can get over (or validate) her fear of geek gatherings. It would be nice
for her to have a better idea of what the lab is about. She would just be
bored at the Space meeting though.
