The trick is to map the linear gradient onto the object ACROSS the
curve. (In the case of the example object shown, that's the X axis. --
The paragraph saying that the object "benefits from a Y axis pro-
jection" is incorrect.)
It's kinda like displacement-mapping in reverse: use an object with
the desired curve to create an image that will recreate that same
curve when displacement-mapped onto a flat object.
My "Toaster Tip" was apparently the victim of some well-intentioned,
but unfortunatly erroneous editing.
If you, or for that matter, anyone has a question about that technique,
ask away...
