Minecraft steps map

Hi,

I would like to know if there is a mod (or whatever else you guys can think of) which would be able to mesure how much i walk on a server then export the data to a png showing my direction.

I know this is kind of a weird request but I know there are some great modders out there, I really hope you guys can help me out.

TL;DR: I need some way of mapping my steps. no need for anything else, not even terrain height, just a black and white png.
