Saw some cool dice towers online and thought, "I'd like to build something like that." But, I didn't really want to make a dice tower... so... just a tower then!
I started with a can of tomatoes (I ate the tomatoes) and then some foam I found in my condo's recycling room. Cut them into bricks and glued them on (1). I left spaces for the windows and door. I also cut both ends off the can. Not really necessary to do both sides, in the end.
