Plotting with a simplex

Is there a way I can do plots for variables that are confined to a 
simplex? For example, I often work with variables that are frequencies, 
so, say, x + y + z = 1. I can obviously do an ordinary 3D plot, but since 
the action is confined to the simplex x+y+z=1, this is a bit silly. I can 
obviously use primitives to hack a picture, but that won't help me the 
next time I need to look at a different system that's subject to the same 
constraint. In some fields simplices like this are called triangle plots, 
though they can obviously have dimensions > 3.

Any suggestions are welcome!

Cheers,
Gordon
