This work of art is a contemporary version of the classic fairground attraction "Pulling Strings". Instead of worthless prizes, you can win new life. The embryos represent the cycle of life, the eating of their own tail (Uroboros). The prices hold no surprise; by following the thread you can influence your chances. Natural selection in the hands of people follows other criteria, than when nature is left to run its own course. How does it feel to have the power of selecting new life?
