The last image there is a psycho-galvanic analyzer, based on the work of L. George Lawrence. Unfortunately it seems our attempt to replicate the apparatus was unsuccessful. Perhaps this was due to the lack of signals from Ursa Major, or insufficient lunching (see the article).
In order to display the signals from environmental readings (which did work) such as light, temperature and soil moisture, I added some new ornamentation to the plants in the game.
The horns play and exude nutrients according to soil moisture data, and the inflatoes (inflatable potatoes) inflate according to the light level.
