Do  you gave a spare 40-inch LED LCD screen laying around?  Do you have a way to work really, really fast?  Well, then you have a solution for tonight's Halloween costume.  John Savio has been upgrading his iPhone costume each year as Apple updates the iPhone, and this is definitely the best one yet.  It looks the most realistic, and even has a light on the back to copy the camera flash.

I can't say that this ever anything I'd build, but I definitely admire the workmanship and determination.  Here's a more detailed description of the construction.

[it features] a 40″ LED LCD Panel, a Jailbroken iPhone 4, VGA out from the iPohone, LED Back Camera Light, weighs roughly 75 lbs and uses a mini 12v Battery with 2+ hours of battery life. The costume took a total of 3 days / 40 hours to complete.
