SETIcon was a public convention organized by the SETI Institute and held twice in Santa Clara, California. It was an interdisciplinary conference, with talks focusing on a wide range of issues related to the search for extraterrestrial intelligence (SETI). The programs included panels with prominent scientists from NASA and SETI; talks by science fiction writers, artists, and actors; and panels to explore controversial issues and compare perspectives. The sessions were non-technical and meant to increase awareness, interest, and funding for the SETI Institute. The convention attracted professional scientists, educators, space enthusiasts, and science fiction fans. Astronomical tattoos were not uncommon among attendees.
