China - The City of Tianjin recently commissioned Beijing-based Teon Scenik to produce a light and laser display in the city's Galaxy Park as a permanent tourist attraction. LED was chosen as the lighting technology and TIR systems was commissioned as the provider, while Hong Kong-based Ptarmigan Consulting was appointed to design, install and commission the control system.

Ptarmigan contracted Artistic Licence to provide a Colour-Tramp control system along with a range of DMX512 and Art-Net distribution products. Simon Fraser of Ptarmigan comments: "I selected Colour-Tramp because of its graphics based LED control interface and its ease of programming and automated operation. The main control room is remote from the tower, so the use of Art-Net ethernet significantly reduced the length of expensive DMX512 cabling. The Art-Net ethernet was converted back to DMX512 locally at the fixtures using the Artistic Licence Ether-Lynx."

Ptarmigan Consulting used the off-line version of Colour-Tramp at their dedicated facility in Hong Kong to pre-programme the show. Amendments were then made as part of the final commissioning procedure.
