Interesting that the phone worked. I think some LEDs do send directional light, why they need to put diffusers even on all the tiny pixels of a tv, or maybe I’m confusing things. I was thinking originally about parabolic reflector, but I don’t know if any common consumer items have those.
Oh that could totally work actually with the parabolic reflector. I’m not sure about the leds, I think there might be a lense involved in the phone to direct the flash to a certain radius. It didn’t reverse the image or anything so the focal point must be at the lense itself. Anyway, I’m sure with some messing around we could get such a batsignal torch.
