A transparent numerical display. The display works by stacking seven panes of acrylic, each laser engraved with one segment of a seven segment display. When high power LEDs at the bottom of each pane are turned on, light enters the pane and stays mostly inside the pane due to internal refraction. When that light hits the engraved portion, the light scatters, illuminating that segment.
This project is still a work in progress.
