Betula Contra-Oscilloscope: Operating Instructions

1. The Betula Contra-Oscilloscope is able to extract sounds from birch trees common to the
Umeå region.

2. Contra-Oscilloscopes work differently from a regular oscilloscopes in that they convert an
electrical current of visually recorded objects (in this case that of birch trees) into sound signals.

3. In order to start the process of sound extraction, a birch tree is filmed. The image is projected
onto screen specified as (A) in the Contra-Oscilloscope's makeup.

4. The visual information pertaining to the birch tree is now filtered through a number of glass
lenses and mirrors working similar to a coffee filter - in the end, a unique sound pertaining to
the individual tree is extracted through the visual cues.

5. Once extracted, the sound of the individual birch tree can now be archived and used for
scientific purposes and further research on tree soundscapes. To enable the safe and archival
storage of an extracted sound, an electrical current is led through wire (1.2) into a piece of
moldavite rock (or something equally unique on other planets)

6. In order to ensure maximum archival quality, the moldavite rock is to be stored at 18-22
degrees, in a white cube, preferable with northern exposure
