It is a lighthouse turning (one of my other hobbies) that you can turn on when something pleasantly memorable happens in your life.
The lighthouse is turned linden finished in a whitewash and water based polycrylic.
The Fresnel is a 1/8" clear 3D printed cylinder.
LED's provide the light, powered by cell phone brick.
Center of tower is bored for power cable
Stay tuned for some Arduino animation in the next version :)
Pictures below are self explanatory.
