yellow jacket is a case that transforms the iPhone 4 & 4S into that 650,000-volt stun gun you've always needed.

scheduled to hit the US market in fall 2012 the case is advertised as being able to 
easily stop an aggressive male attacker, and ready for use in less than two seconds. 
its designer seth froom, a former military policeman came up with the product after 
being robbed in his home at gunpoint.

what is the demand for such a hostile product you might ask? well, yellow jacket 
has managed to receive over 100,000 USD worth of backing on the crowd-funding 
website indiegogo which means that there must be quite a few people out there 
who feel the need to transform their phone into a weapon.

the iPhone's designers could never have conceived half of the the weird and wonderful accessories 
that have been designed for use with the iPhone since its launch, but even in the name of self defense 
a stun gun seems a bit much, doesn't it?
