Morph Rooftop Bar, Kempinski Hangzhou
Lines of light flow across the ceiling and interior of Morph Rooftop Bar. Developed with artist Deyan Raykov, the lighting concept draws on Hangzhou’s relationship with silk. Refractiv designed and programmed the system, moving the room between ambient, event and sound-reactive states.

The House of Silk
Deyan Raykov and Refractiv developed a lighting language of paced movement and soft transitions. Continuous lines across the ceiling, bar and surrounding interior connect the venue’s three zones, giving them a shared rhythm.
The scale of the installation makes the relationship between those zones central to the work. Light travels through the interior as a coordinated composition, with changes in pace and intensity held within the same visual character.


From a quiet room to an event
Refractiv built the pixel mapping, content and control in TouchDesigner. Individual addressable elements can form gradients and moving patterns across the full layout.
Programmed sequences provide ambient and event states. Sound-reactive modes connect music to the movement of light, allowing the venue to change with its programme.

Planning the physical system
Refractiv developed the system design and technical plans for implementation. Xuan Xu Ltd led the project, and a local contractor carried out physical installation under the general contractor. The lighting sits within Ashley Sutton’s interior design.
