Female Extension is perhaps one of the more renown pranks within the history of net.art. For the project, artist Cornelia Sollfrank submitted more than 200 applications by fictitious female artists to the net.art competition EXTENSION sponsored by Galerie der Gegenwart (Gallery of Contemporary Art) of the Hamburger Kunsthalle (Hamburg Art Museum). She created not only a name, email address, phone number, and address for each applicant, but an example of original net.art work as well. Despite the disproportionate number of submissions by female artists, only male artists were selected as finalists. After the decision was announced, Sollfrank went public with the spoof.
