"It's a wet Saturday afternoon at a hacker convention
in an industrial section of Hamilton, Ontario. Treven Watson's
Lucite badge is flashing: blue, green and red. The LED lights are
controlled by a circuit in the laser-etched ID. That little bundle
of electronics is about to be probed and reprogrammed by Watson and
the three dozen other coders, anxious to make it do anything but
alternate primary colours.
""There's a tradition in hacker conventions of making badges
that can be expanded, can be hacked to do other things," said
"Watson is a member of the Hamilton hacker space think|haus.
Attendees at the convention each got their own badge and spent
hours seeing who could hack it best."
