Thanks Ben...And for those interested this is the first of the results that I found on GOOGLE:

Mark, the gist of it is pinch-and-upset.  Pinch the pipe in an even
ring, and then when you upset that area, it folds itself in on the
ring and tends to bulge just a bit.  If the rings are not even, you
will get really neat organic lumpies that don't look much like bamboo,
so experiment :)  I did some pinching with a straight pein and the
edge of the anvil, and it worked but I was not making even rings.
This generally works best on thick-walled pipe, but I'm sure it could
be finessed into thinner material.
I found a video with a quick google search, of a guy making metal
bamboo -- he uses some sort of fuller-tongs thingy instead of a
chop-style or guillotine (no hammer blows to pinch), then upsets the
piece after quenching all but the pinched area.

cheers, folks!  Oh and I concur, nice work Kirsten!
