Thiago Rocha Pitta at Marianne Boesky Gallery

Brazilian artist Thiago Rocha Pitta’s new videos track minute, artist-introduced changes to tiny segments of the landscape in Argentina. Here, a cascade of sand runs like a never-ending hourglass. (At Marianne Boesky Gallery on the Lower East Side through March 22nd.)

Dylan Stone at Josee Bienvenu Gallery

What does your bookcase say about you? London-based artist Dylan Stone memorializes his film producer parents’ collection of books, LPs and video-cassettes in a huge painting at Chelsea’s Josee Bienvenu Gallery (seen here in detail). So much pre-digital media rendered in the ageless media of watercolor makes a poignant comment on longevity. (Through Dec 13th.)

Geoffrey Farmer at Casey Kaplan Gallery

Canonical works of western art from throughout the ages – cut from the pages of art books – rub shoulders in Vancouver artist Geoffrey Farmer’s ‘Boneyard’ installation at Casey Kaplan Gallery in Chelsea. The effect is surprisingly odd as it seems to warp space and time via the simple device of propping paper cutouts on a white tabletop. (Through Dec 20th).

Valeska Soares at Eleven Rivington

A selection of 365 dust jackets mounted to linen supports by Brooklyn-based Brazilian artist Valeska Soares at Eleven Rivington muses on the passing of time. Not only do the titles refer to temporality, but dated fonts and designs act as a measure of change over a few decades. (On the Lower East Side through Nov 23rd).

Agniszka Kurant at Tanya Bonakdar Gallery

‘The End of Signature’ by New York based Polish artist Agnieszka Kurant compiles hundreds of signatures into one long scrawl, appearing on the gallery wall in black coloring on a long, tube and replicated by this machine. Kurant’s piece bears witness, neither critically nor enthusiastically, to the increase of typed communication and digital signatures. (At Tanya Bonakdar Gallery through Oct 18th).
