Have You Seen This?

Oh my goodness. This may be the best thing since clap on clap off lights! Granted I would never feel comfortable using it on my front door, but holly crap! If Matt ever gets around to building a hideout for our boys, I am TOTALLY buying this thing! And if it's not for sale, well by golly, I'll knock my knuckles til they're bloody to get into this guys apartment and steal it! Probably won't be too hard. I'll just make up some crazy beat from a Lord of the Rings movie and walk in on him and his friends wearing long capes and elf ears. How do you say "can I borrow this?" in Elvish?
