just a train, the idea came from song for the deaf by queens of the stoneage, in the intro theres this part that sounds kinda like a heavy metal growl and for some reason I thought: that sounds like a train, which lead to the thought, I have that picture of a train I havent done anything with, which lead to photoshop, the bane of my existance, the picture took WAAAAY longer than it should of because of the fact some anonymous "sporting/cooking supply store" put around 1700 entirely useless filters in the program and until today I held out hope that maybe somewhere, somehow one of them would have a use. finally I started over and found some that went together nicely.
