Snog is a small chain in the UK, riding the wave of “unsweetened” frozen yogurt shops.  The difference is in their store design.  Their latest store, Snog Soho, includes a fantastic ceiling composed of 700 color-changing glass pendants, backed up with some incandescent lighting.

Cinimod Studio was the UK-based lighting designer, and details on the custom lighting tech can be found at e-luminate.
