[Unoffical Contest] -Inator contest!

This is my first contest! BACK STORY TIME! So, I've been watching Phineas and Ferb a lot lately, and I liked seeing all of the ridiculous contraptions on the show. I figured some of the best builders I know are here, and I would like to see what you can come up with!
RULESIES:
Does something aside from killing/destroying things, unless in a very unique way.
Has to use some type of laser or projectile, Lua or not. I will judge Lua entries and non Lua entries separately.
Level must be a derivative of this level.
Have fun!

(P.S. if anyone else wants to help judge you can, but you can't enter the contest.)

DEADLINE: August 20th (sorry for the mix up!)

As of August 25, this contest is closed. Thanks to everyone who entered! I will be judging your creations soon.
