Art Buzz: Buy art on your iPhone & real bullet holes from Iraq

Geert Goiris: For his latest photo series, “Resonance,” Belgium-born photographer Geert Goiris offers up seemingly benign snapshots which, upon closer inspection, reveal uncanny, or off-putting elements. Most peculiar of all is an image of plastic office chairs arranged AA-style around an unremarkable wood table (which, you soon realize, has no legs).

Hide/Seek: Since making its debut at the Smithsonian last year, “Hide/Seek: Difference and Desire in American Portraiture” has made its way to the Brooklyn Museum. Featuring images taken of or by gay artists, the latest iteration of the exhibit includes David Wojnarowicz’s controversial video short, “A Fire in My Belly,” which was removed from the original showing after Republicans complained about the inclusion of a crucifix.

Painting with Bullets: Last year, Piers Secunda traveled to war torn Kabul to make plaster casts from bullet punctures in the walls of different buildings. To be sure he was casting exclusively Taliban-made bullet holes, Secunda visited each site immediately after an attack. The completed works are now on view at London’s Aubin Gallery.

Art on Mobile Electronics: It seems the future of art hinges entirely on your iPhone. A new app allows users to buy, store, and view custom artworks by the likes of Tracey Emin, Bill Viola and Tim Noble, all of which come with their own digital certificate. What, you thought people still hung art on their walls?
