That is SICK!! Mine isn't a "10-wide" (meaning 10 lego "bumps" across) but I did a dodge Viper that's a 4" across. I custom-designed in using the LegoCreator software (available on Lego.com) and then you can just order a "kit" of the parts you used. I thought it came out awesome.
Of course it's in PA, so I don't have it to take pics of...
