I was just waiting for someone to use those wheels! I saw them in the LEGO mag, and I thought "Man, those would be perfect for a NXT creation!"
I saw that model before most people did. He came to my sumobot competion. Its cool he put it online. :-)
some guy already used those wheels in a video on youtube called something like the "green dragon" with nxt and the PF xl motors--looked like it could haul A$$.
