Waterdrop Hinge & Reflection Simulation
Physics & Optics
Drag angle handle to fold/unfold device
Source Grounding: Inspired by Mashable's Hands-On Review: "Apple iPhone Duo hands-on: I barely noticed the crease." Evaluating how a generous waterdrop radius (≥3.2mm) and reinforced tensile backing suppress surface reflection angles.
