My admiration for Carl and his influence on SETI drove me to illustrate this quick sketch of the antenna arrays which persistently seek transmissions from beyond interstellar space.

This picture represents my interpretation of again, our feeble attempts to communicate with the cosmos based on our seemingly advanced technology. I say "seemingly' because the equipment and technology we are applying to this type of cosmic reach may be viewed as ancient and adolescent within the next 30 to 100 years or less.

The ocean and quote by Carl explains itself :)
