Idea: Space Invaders

An idea sparks in my head after reading this: http://en.wikipedia.org/wiki/Invader_(artist)

Why don’t we make up a story based on this?

Imagine the artist were actually an alien in disguise, and he’s really invading the earth by cloning and distributing alien’s bases all around the world in the form of street arts…

However, his plan is unexpectedly detected by a kid, who will be our hero saving the world from the alien….

Sounds interesting, huh?
