It maybe wishful thinking, but has anyone seen a race track lap timer and leader board on their travels?

I have a cool one in SL that had a start/finish line and checkpoints to place in key locations around the track to stop short cuts. It would display the top ten lap times/names on the leader board.

I have been to a few race tracks in open sim and have never been able to get hold of one. I have never seen one in any malls/freebie places either.
