Both crop circles seem to reference elements of New Physics.
The top image represents the scheme of a free energy device.
The bottom image represents alien/human consciousness (according to Q-FFF theory).
The pipe could be introduced as a metaphor to thoughtful decission making.
According to Q-FFF theory, wavefunction collapse and human decission have in principle the same entanglement (observer-subject) relation with other COPY universes with the same Big bang origin.
Thus this crop circle metaphor says that our multiverse is based on a total of 8x entangled anti-symmetric COPY universes.
