This concept matured into a first prototype during the master thesis. Two "aquariums", which communicate with each other via the Internet, are to transmit vital signs in the form of the heart rhythm to a friend and visualise them with the help of the bioluminescent algae.

The algae are stimulated by the loudspeaker in the respective aquariums and can thus reproduce the speed of the heart rhythm exactly.
