The Laser Harp

Hello people. I know that no one looks at my posts but I'll just talk. 

So you might be wondering what the Laser Harp is? Well it's a different shaped harp, in fact it doesn't look anything like a harp. As you can see it's just a bunch of lasers, but when you block one of these lasers it sounds a harp note. You can also change the sounds. 

I think it would be a cool little thing to play with (if you were rich). 

This is a little video that i found.
