Here is a cool wearable – the WiFi-detector shirt that will let you know if a network is nearby. The detachable detector / display combo runs off three AAA batteries for "hours" — and ThinkGeek should have them for $30.

We had the dress that becomes an inflated chair and now we have the sound-activated inflatable shirt that blows a balloon for one second.

Designed by Tomoko Ueyama, this Watashi-chan inflatable shirt responds to six frequency bands of sound, even one human ears can’t hear.

Watch out for those dog whistles.
