A metal Hula-hoop that functions as an antenna. Has a Bluetooth transmitter to stream picked up RF to your phone. Powered by the same thing they use for self-winding watches. Only bigger.-- 21 Quest, Sep 17 2009 may the Society for the Prevention of Cruelty to Racial Stereotyping strike you down [+]-- FlyingToaster, Sep 17 2009 Muchabliged, good sir. Muchabliged!-- 21 Quest, Sep 17 2009 Keeping the Hula hooping around the cellphone would be a bit hard on the old arm.-- wjt, Sep 17 2009 That's what the Bluetooth is for. So it doesn't *have* to be around the phone.-- 21 Quest, Sep 17 2009 So a sore neck then?-- wjt, Sep 18 2009 does the hula action boost the signal? or is that just to make it extra fun?-- ixnaum, Sep 18 2009 Probably both. Would also encourage fitness.-- 21 Quest, Sep 18 2009 random, halfbakery
