Five Second Project on GSG: http://greyscalegorilla.com/blog/2010/09/five-second-project-primitives/
"Letâ€™s stick to the basics for this one. Sometimes you can get too carried away with complex models and scenes. Letâ€™s see what you can do when youâ€™re limited! Primitives only with this one."
Since I wanted to do a 2D design, I flattened the 3D primitives. Originally the conecpt contained a pyramid as well, but five seconds pass damn qucikly.
