Found this bike on teh interwebs.
Michael Slater built his own break-apart frame that incorporates no less than 6 S&S couplers. This takes the folding-bike-as-a-pile-of-parts to a whole new level. With the 20" wheels, the bike can fit in a small suitcase.
His blog shows the build process from random tubes to whole bike: http://karavshin.org/category/bike/le-chacal/
