That level editor looks pretty impressive. Did not know you could import your own artwork.
I'm not entirely sure you can Heiseman ... for example, that MotorStorm logo consists of ultra-fine sheets of wood, layered and glued on top of each other. Same goes for the cow. You can, then capture numerous objects and save them in "My Objects" for later use ... which is what I did for the MS logo and the cow, so I could include them in prize bubbles around the course for other users to collect.
