SVK - a new one shot comic by Warren Ellis that deals with some sort of superspy will come with a blue light device that when shined on the comic will reveal hidden though balloons. So you can read the comic once and then read it again seeing what the characters are thinking.

Each comic (not sold through shops but via a website) will come with the device for around 10 british pounds ($25)!!

I will be checking this out - sounds damn cool.

Reminds me of DARK DOMINION from Defiant, where you could put on special glasses or something to see the evil critters.
