This gorgeous reuse of an industrial gas tank as a canvas for a light project show called 320° LICHT | SPATIAL EXPERIENCE melds the spatial and the virtual to amazing effect.

From the project page:

"The ‘320° Licht’ installation of URBANSCREEN uses the cathedral-like beauty of the Gasometer Oberhausen as the starting point for a fascinating game with shapes and light.

Within a radius of 320 degrees graphic patterns grow and change on the 100-metre high inside wall of the Gasometer.

The observer experiences the interplay between real and virtual space, in which the Gasometer seems to dissolve into its own, filigree structures and yet finally always reverts to its clear shape. ’320° Licht’ is achieved with kind project support from Epson Germany.

With approx. 20,000 square meters of area played upon, the installation is among the world’s largest and technically most sophisticated interior projections - interconnecting 21 powerful projectors to one projection screen."
