D-Light manipulates an RGB LED in six dimensions, allowing the user to draw a hologram of their choosing. A camera positioned pointing at the gizmo takes a series of photos and compiling them together in order for the user to see the light trail. The manipulation of the LED is done via two joy sticks - one controlling the Z axis and the other controlling the X and Y axis. Resulting in holograms of the users drawings as seen.
