Rainbow

Rainbow is an inclusive product designed to support the Motor Activities Training Programme (MATP) for children with motor coordination challenges. By combining grabbing actions with color matching, Rainbow helps users improve hand-eye coordination, visual tracking, reaction speed, and decision-making. Research shows these children are naturally drawn to bright, bold colors and vivid hues keep them engaged and make targets easy to spot. Instructors spin Rainbow’s 40 cm plywood disc, mounted on a recycled PVC pipe axle, so colored balls roll into view one by one. The child grabs the matching ball and drops it into one of two interchangeable trays, whose openings (10 cm or 6 cm) adjust the difficulty level. Every component uses eco-friendly, low-cost materials: the main disc is sturdy yet lightweight plywood, the axle is recycled PVC, and the trays are plain corrugated cardboard. All parts could snap together via matching grooves, making assembly tool-free and DIY-friendly. To build your own Rainbow, cut the plywood disc, drill and glue the PVC axle, craft cardboard trays with circular cut-outs, carve shallow ball recesses, and slot the trays into the discs perimeter grooves. This accessible design turns rehabilitation into a playful, rewarding experience.
