Spaced Invaders

I have an idea for decorating the bare Osageland walls. Who here has played the old 80s arcade game Space Invaders, or one of the numerous variants such as Galaga? You know, where is a block of alien ships slowly falling and you have to fire upwards and burninate them.

Well, how about we make cutouts of the pixely defender shooting up at the aliens and put them up on the wall at the base of the stairs? The only annoying thing is going to be getting a ladder to stick the aliens to the top of the wall.

Materials for the cutouts: I was thinking using some of my extra roadmaps I've collected. Or, you can go the distance and actually make individually colored pixel squares or paper or tile and assemble them matching the images instead of just the outlines.

This is Space Invaders
