look at the overpic package -- ctan macros/latex/contrib/overpic/

it's not over-blessed with documentation, but there are a pair of
example files (opic-abs.tex and opic-rel.tex) which i used to teach
myself.  i then went through it with some collaborators, and they've
declared it "really neat", and have already used it in production (in
the volume they sent to press in august).

whatever, _i_ think it's a brilliant application of a simple idea :-)
