Impossible Borromean Triangles
Each Impossible Triangle is from 3 modules and each module is from 8x1 rectangle. [ 24cm x 3cm ]. The module is a slight variation of Nick Robinson's Penrose Triangle:- www.flickr.com/photos/7943052@N08/4821323561/in/photostream
Nick's version is from 4x1 rectangles. Except for the difference in dimensions, I made a slight modification in one of the folds to allow a better fit for the modules. The 3 triangles are held together but they are not linked. If any one is removed, the whole assembly breaks apart. Thanks again to Nick.
