Now, the product does have some flaws– low power (less than a Watt), bad collimation and it burns through batteries… but it’s portable.  And decently cheap.

Of course, you could just buy a bunch of green lasers and figure out how to collimate their output and build your own laser cannon…

Makes me smile, because one of my good friends in high school is deaf and has implants.  When her daughter was born, she didn’t react to sound and they had to do testing to see (in her words) “if she’s deaf like mommy or just stubborn like daddy.”  Turns out, she was just ignoring everyone.
