I'd like to look at that...since it's not a lot of bull...unfortunately, the
link didn't work.

[As John pointed out, it's not the smallest man-made object by any means,
but still it's pretty impressive. (Not quite "no bull" but almost...) They
seem to have achieved a high degree of surface refinement. I go with a less
restrictive definition of sculpture, myself, so the IBM logos at the atomic
scale would probably qualify as far as I'm concerned. Has anybody been using
this 2-laser technique at a larger (maybe even visible) scale?

Instead of using the whole link (which doesn't work for me either, now that
you mention it), try going to http://www.skynews.co.uk and typing
"sculpture" into their search box.]
