This project is about creating a long-lasting artefact that does something interesting.

The current plan is to create a glass sphere with a cavity in the centre containing some electronics.

Here's a list:
  * Self-powered,
    * Solar,
    * Peltier and thermal mass,
    * Supercapacitor.
  * Resilient,
    * High or low pressure,
      * Bottom of ocean,
      * Vacuum.
    * Shock,
      * Drop-proof to at least 1m onto a hard surface.
    * Background radiation.
      * IR,
      * UV,
      * Cosmic rays.
  * Long-lasting,
    * A decade at minimum, preferably much longer.
  * Interesting,
    * Least to most interesting:
     - A light,
     - A blinking light,
     - A light that blinks a morse coded message,
     - A screen that displays a message,
     - Interactivity,
       - Covering the solar panel can be an input.
     - Displaying a random wikipedia article.
