This is one of those gadgets that’s entirely capable of being awesome, but only on one condition. You have to be below the age of 12 years old. Beyond that, you’re just going to come off as a dork with a plastic disk attached to your shirt. Then again, if you’re comfortable with your high level of dorkishness (that’s a word, well, it could be) then wear your Iron Man Movie ARC Light with honor. You can purchase it for $7.59 through Entertainment Earth. It won’t be shipped until sometime in March.
