I don't remember the name of the frame, but I recall seeing one that was made of a top tube, a down tube and about 19 other pieces of tubing cobbled together with a section of tubing just long enough to hold the seat post - all for the purpose of allowing for a slightly shorter wheelbase. (This one was way more contrived than a Flying Scott or a Baines flying gate (both of which I also think of as being quite gimmickey).

I recall a number of people oohing and aahing over it, but it struck me as a bicycle with about 4 times the ordinary number of points where stress could take it's toll and joints could go bad.
