01 / Overview

Rainbow is a magnificent circular arc formed by the refraction and reflection of sunlight by raindrops, which is a magical optical phenomenon in nature. Looking up at the artistic shapes of light and shadow above, watching the interweaving of colorful lines and full spectrum lighting art, and enjoying a stunning visual experience.

02 / How visitors use it

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

03 / The science behind it

Rainbow is an optical phenomenon in meteorology. When sunlight shines on water droplets in mid air, the light is refracted and reflected, forming an arched rainbow spectrum in the sky. From the outer ring to the inner ring, it appears in seven colors: red, orange, yellow, green, blue, indigo, and purple.

04 / Built for a public floor

Every unit leaves the factory after a running test: mechanisms cycled, electronics burned in, edges dressed, fixings torqued and marked. Wear parts — bearings, sliders, lamps, belts, touch panels — are modular and listed on the spare-part sheet, so a venue technician can replace them without returning the exhibit. Crating is plywood with foam blocking; the loading plan and packing list travel with the shipment.
