Direct Quotations

This is a non-judgemental but guided attempt at establishing whether or not it is possible for buildings to pull off looks borrowed from people, animals, man-made and natural objects. The thought of architecture taking huge reality bites - with a conscious intent to do so - is quite embarrassing to most people who attended architecture school. Historical examples - quite deliberately included here - can of course be waived off with an understanding smile and forgotten. When it comes to recent examples of such direct quotations, however, is it possible to draw immediately the line of subtle nuance that distinguishes clever context-aware ingeniousness from kitsch?
