The half-shipping container, half-Parthenon structure above is one of the venues for this year’s Biennale (sadly ending this weekend, and completely neglected by myself for the past two months). One of the exhibits inside is an expression of the perfect city in a series of sketches and wood models of observatories. Something like that.
The aliens posing next to the Supreme Court building can be seen at City Hall. A couple more photos in my Flickr stream.
