This used to point to http://members.cox.net/crandall11/, but that site is no longer available. The links have been updated to point to Origami Resource, where the pages have been preserved. Apparently these were created by Clay Randall.
I'm cleaning out my e-mailbox, and I've come across this link of stuff I've always wanted to learn: money origami. It has links to other money origami sites, too. If I file it away, I'll lose it forever, so I figured it would go well here.
