For coolness factor, I'd put this tandem unicycle somewhere between Bi-Cycle tandem bike and the Face-to-Face, while for pure crazy it's just shy of the Uno bike in single-wheel formation. Unfortunately, Corbin forgot to save his "great post about the construction details," so you're on your own for now building a tandem unicycle for you and your sweetheart. I'm pretty sure that step one was "lose all rational sense of physical limitations," so feel free to get a head start on that until the full instruction list is up.
