Birth of Flight depicts the American Sign Language (ASL) sign for "butterfly," rising out of a chrysalis of feathers. The sculpture is indicative of the human desire to fly. Frahm has chosen to focus on the emotional rather than the experimental aspect of that desire. The use of ASL to express the urge towards flight was inspired by the artist’s teaching of sign language to his infant son: a gesture transcends languages and is accessible to all.
