New tiles

art:
- im trying a new method for creating tiles inspired by this game: http://www.rocksolidarcade.com/games/robokill/
here's how im doing it:
in blender: im making a contour, extrude/bevel it, render with an ortho camera and sun for a light
in gimp: fix the colors, make some detail/dirt, add some hilight and thats it. all made with the mouse. still look a bit sterile but it could pass for stylishness
