Hi Tom,

Not really an answer to your question (which others have already answered)
but, really, taking the idea further. I have seen some very effective
interpretive displays where images have been made by drilling holes of
various sizes through sheet metal - the effect basically works the same as
the old newspaper photos, where the photos are represented on the newspaper
by dots of varying sizes - I believe the technical term for this is
halftone.

You can get this effect in Photoshop; this webpage gives a brief
discussion:<http://designertuts.com/258/newspaper-photo-effect>

And here's a commercial example of the perforated metal:

(Though I think the ones I saw were much better.)


Just thought you might find it interesting.



Cheers
