3D Printable Lenticular Indicators

MIT CSAIL researchers developed ShiftLens, a technique for 3D printing lenticular objects that change color or pattern when a transparent lens layer is shifted relative to a patterned color layer beneath it. The shift can be driven by a knob, switch, or roller, enabling effects like a visual indicator showing whether a bottle cap is properly closed. No public design tool exists yet, though the team built an internal Rhino plugin for the project.
