A standard catalogue model: the dimensions, control package and finish are fixed, which is what keeps the price and the lead time predictable. Size, colour and interface language can be adapted without a new design cycle.

01 / Overview

Rotate the wheel, fill the exhibits with water, and observe the changes in the wall image through a water lens. When light is obliquely incident from one medium into another, its propagation direction will be deflected; At the same time, by injecting water, the thickness of the water lens changes, thereby altering the focal length of the convex lens, resulting in a change in the size of the image seen through the lens.

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 / 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.
