What’s the application? The use of lasers to provide an entertaining light show for humans, dogs, or cats.
What problem(s) is it the solution to? 1) “How will I entertain my dog or cat?”
2) “How can we distract people from the fact that Roger Daltrey has no voice left?”
Why are lasers essential? Lasers provide coherent beams of light, which remain small over very large distances, allowing you to project a small spot or a tight beam across a room, or even a football stadium.
Why is it cool? Duuuuude! Lasers, duuuuude!
Why isn’t it cool enough? 1) It’s fundamentally just a toy. 2) No amount of laser light could keep the Who’s halftime show from being kind of sad.
(This post is the first of twelve highlighting amazing laser applications, in honor of the 50th anniversary of the first laser. These posts serve as a lead-up to an audience poll asking what the coolest laser application is, so if you like lasers and radio buttons, watch this space over the next week or so.)
