In the 90's I wrote a book with the my partner at Paleotechnics and Wife at the time, Tamara Wilder. We need to reprint and were sorting through the original copies so I made a quick video showing some of them. We have a few copies of the book available on http://www.paleotechnics.com but I took it off of Amazon until we reprint, though some sellers may still have a few strays for a while and there will be the inevitable copies selling for hundreds of dollars claiming that it's out of print. Which, I guess it almost is now. Hopefully we'll have it back in print soon.
