Peel Street Caves

It's hard to resist a note that says a "new cave" has been "uploaded," but the Nottingham Caves Survey—previously mentioned here—has announced just that, putting 3D laser scans of the incredible Peel Street Caves on their website.
Like smoke rings breaking apart and slowly looping inside the planet, their near-endless recursivity makes it almost impossible to see where they begin.'

Sense of the CIty

'Sense of the City explores urban phenomena and perceptions of the city which have traditionally been ignored, repressed, or maligned. Challenging the dominance of the visual in the urban environment, the exhibition proposes a re-thinking of latent qualities of the city, offering complex analyses of the comforts, communication systems, and sensory dimensions of urban life—thus advancing a new spectrum of experience and engagement.'
