You can change the color of the lamp by placing a colored disc into the circular recess in front of the lamp body. When no disc is placed in the receptacle, the lamp changes color randomly. Place the white disc to produce a white light and the black disk to turn off the lamp. You can also turn the lamp into a stroboscope or produce other special effects by combining different sequences of colors.
The body of the lamp and the RFID disks are made out of scrap wood I had in my shop. The shade is made from a transparent drawing tube and tracing paper.
