This is a new technology that I can only describe as “unbelievably cool.” The idea is simple, if you’ve ever held a glass up to sunlight: when light passes through a curved, transparent surface, it gets bent and forms patterns when it lands. What this company has done is worked out an algorithm that lets them delicately shape pieces of glass so that the resulting pattern forms any image you want.
The result feels like magic: you’re holding what looks like normal glass in your hand, but as the light shines through it, it projects an image.
There’s nothing actually magical at all, of course; the challenges are all in some algorithmics to compute the right surface shape, and in the practicalities of shaping glass so precisely. But as the video evidences, the results are beautiful. I can’t wait to see this hit the market.
