Here’s a fresh idea – an art gallery that you can access on your iPhone. Using a gallery in Berlin as their home base, Adidas has curated a collection of some of the finest street art worldwide, fittingly titled the Urban Art Guide. The selected works will be constantly updated by Adidas’ editorial staff, and in the spirit of populism, users can leave feedback and rate the works. The launch party is being held at the Dice Club in Berlin, and will feature artist Hitotzuki and performances by Seuil, Tolga Fidan, Varoslav, and Alex Dee. Access this gallery when it drops right here.
