Back with a bang after a little delay, we bring you Travis Pastrana motocross madman and his Nitro Circus. This bangin' mash-up design features a lot of fun Flash transitions and in-your-face graphics. Exploding off your screen, this site reflects much of the fun and daring of extreme sports' high-impact design. Our only knock was the music doesn't stay off as you move from area to area, and the site load is pretty damn huge. But hey, that's how these guys live... large!
