A while back I asked for some tips on folding correctly the Jackstone by Jack Skillman. Vishwas Deval replied commenting that Jackstones could also be made from other polygons and provided a link to his gallery.
I've folded the one from an equilateral triangle and the one from a pentagon. Both models although difficult produce nice results. In case anyone want to check them, I uploaded pictures to: http://www.flickr.com/photos/georigami/9375722613/ and http://www.flickr.com/photos/georigami/9457499933/ -- Jorge Jaramillo
