[Cyborg] DIY pulsed laser pistol

There's another art piece called the YAL-1, which is a megawatt-class 
laser built into a 747 with a 3-5 second pulse time.

After spending $5B on development, and verifying that it can, in fact, 
damage missile while in boost phase (not descending phase), but only at 
relatively close range, Defense Secretary Gates said that "I don't know 
anybody at the Department of Defense who thinks that this program 
should, or would, ever be operationally deployed. The reality is that 
you would need a laser something like 20 to 30 times more powerful than 
the chemical laser in the plane right now to be able to get any distance 
from the launch site to fire.

"So, right now the ABL would have to orbit inside the borders of Iran in 
order to be able to try and use its laser to shoot down that missile in 
the boost phase. And if you were to operationalize this you would be 
looking at 10 to 20 747s, at a billion and a half dollars apiece, and 
$100 million a year to operate. And there's nobody in uniform that I 
know who believes that this is a workable concept."

bonus: the turret looks like the eye of Sauron!
