Champagne Valentine recently released the app component to its digital efforts promoting Polish artist Mirsolaw Balka's How It Is at the Tate Modern, the biggest large scale work to be featured at the museum's Turbine Hall.

CV had released the How It Is website in October. The partner app, for the iPhone and iPod touch, is the first launched out of the Tate. It features a virtual tour and video interviews similar to the How It Is site, but steps it up with a game that becomes unlocked through GPS when visitors are near the Tate Modern.
