Weird Request - Node Finder???

I'm not into all the norecoil hacks and all of that, what I really do like is farming though, is it possible to make a esp-like hack to see nodes? (like xray for minecraft), and if it is possible, would someone release? I'm willing to pay aswell as long as it's private.

Yes there is such thing

where could one find such a thing???

That's straight ESP , it's one of the features that come with almost every cheat.
