How to burn flat images in wood?

[samualt]

Has anyone ever added a wood burning type tool to a cnc router? I mean like a torch or something. I know the best way to burn a flat image into wood would be to use a CO2 laser, but that is very expensive. There must be an alternative to expensive lasers.
I see allot of software for making images in wood like ImageCarve, DeskArt, or ArtCam. But those are pretty much 3D relief. I was thinking more of just a flat burned image like a CO2 laser can do.
Any ideas?

Anyone remember the "Ungar Woodburning Set" (from the '50s-'60s, IIRC). It was a low-wattage soldering pencil with various shaped tips.
Mount a soldering iron on the z-axis. Speed and feed could be found with trial-and-success.
