Looking for a mini car...

Days ago I watched a video where a minicar was shown, it was one guy showing machines that he downloaded. I tried to find that video again and spent a lot of time in it but I cannot find it. I rememebr the voice of the guy and even what he said but I just cant find it. Also tried google.

So i ask you for help. The car was very very small, it had at least 2 wheels (dont remember if 4 xD) and to turn had a perpendicular wheel in the back (it seems like a jeep spare wheel). I can make a copy, of course, but i cant explain why I want to see that again.

Do somebody have seen this?
