Aristide Antonas is an architect, writer, Doctor of Philosophy and associate professor of architecture at Greece's University of Thessaly. His Flickr page has a number of interesting architecture projects on it, like this double-decker-bus-cum-hotel:Some other out-there projects he's posted are proposals for people living in crane structures and converted oil tanker trucks:
While the documentation on each project is copious--the bus project alone comes with a 1,900-word description--credits are lacking, so it's not clear if these are Antonas' personal/work projects or projects that he's shepherded as a professor. Either way they're fascinating. See more here.
