This has got to be a joke (or an artistic concept, I'm not quite sure): A wearable device to detect Wi-Fi networks, shaped (for all unwary observers) like a chrome purse.
Definetly not something all wardrivers will wear, given that the vast majority is (vocally) male, irregularly bearded and with a six-pack (of beer).
Of course, there are studies demonstrating that around 2% of the population is gay, so they're probably aiming at a niche market. :)
I've yet to feel the need for stuff like this on the Mac (my only itch was successfuly scratched by PowerPoint Remote, but it looks like this kind of application is still popular.
