This is an idea for a running race plugin. People would getter around somewhere them givem directions, maybe like GeoCaching, or real X, Y, Z coordenates to a random place. Prices could be itens or money.
I was playing a game with friends last night where we would just yell out random co-ordinates (X and Z only) and using gps raced each other to the point. We found it a quite a lot of fun especially when it went across water and mountain rainges. That got me thinking that this would be a fairly simple plugin to make by typing a command which set the co-ords (eg /startrace 1000 n [put globally state a location -+1000x,-+1000y from your current location) then when someone gets to that location it tells everyone who won. "n" could be the number of races. I went looking, sure that someone would have done something like this already but does not look like it. To make the game more advanced, a torch could be placed on the surface or a chest with contents from the players inventory could be used as the prize.
So it will be named RunForestRun I think. I hope that guys from Warner bros. havent got a trademark for that phrase
