The ancestral commonality between humans and chimpanzees is undeniable, with dramatic evidence exhibited in our chromosomal similarities. Prime Commonality is visually inspired by this high degree of correlation as shown in human and chimpanzee chromosomal banding patterns. The sculptures are internally lit and change colors to produce intense visual effects that take advantage of the physical interaction between colored light and translucent filters. The installation is sonically accompanied by a 14-channel fixed media sound art piece composed entirely of manipulated samples of both the human singing voice and chimpanzee vocalizations. Prime Commonality highlights both our similarities and differences with the shared natural world. Selections from the original installation as well as sculptures inspired by this concept are installed in Newport Beach, CA, Atlanta, GA, and White River State Park in Indianapolis, IN.
