From Cranky Professor:
[The problem with} this architecture of the mind, conceptual art we're forced to live in, is that it ages especially poorly. Imagine these 'ugly junctions' after the funicular has been running for a few years, jostling, shaking, and generally loosening up fitted panels - and the expense of replacing those unique glass panels when they have problems!
Obviously we need to promote the "sustainable conceptual art" movement.
