Here's an interesting fact: each year, Americans spill over 9 million gallons of gasoline, which is the equivalent of an oil supertanker. I've captured about a quart of that gasoline for the textures today. This oil may not have been used to power a car, but perhaps you can offer it some redemption by finding some good uses for it in your designs.
