Any kind of display fits in the square frame.
So, I wanted to make a display that doesn`t in the frame.
SteganoScan Orbs consists of tens of balls which glow like moving pixels. Even each ball moves randomly, balls can show 2D images.
This system is composed of two units: PVLC (Pixel-level VisualLight Communication) projector* and balls made up of LEDs and photo sensors. The PVLC projector can embed information pixel by pixel in the projected image. When users put a ball in the projection light, it captures and displays the information simultaneously. Moreover, by rolling the balls in the projection light, glowing balls can form an 2D image.
