If you are an Avengers fan, then this LEGO Arc Reactor will blow your mind. An artist by the name of Mr. Attacki decided to recreate the gift that Pepper Potts gives to her boss Tony in the popular Iron Man movie. The replica is made out of LEGO with an LED light that gives it a glowing touch.
In the Marvel comic book, the reason for the arc reactor is to keep the shrapnel from piercing Stark's hear, which would kill him. This LEGO Arc Reactor might not be able to strap onto your chest like with Tony Stark, but it can act as a security night light to keep the boogey man away.
