We all seem to have our little niches in this group, so how about a show-and-tell? Bring in your wearable devices, be it Google Glass, Nike Fuelband, or a hearing aid. There are so many categories of wearable computers, it'd be useful to see them all. If you've written some software for these devices, show that off too. So much the better.
Join us even if you aren't wearing, it's a good time to play around.
