The exhibit contains pictures, animals and models of species known to engage in homosexuality, showing among other things southern right whales and giraffes engaged in same-sex pairing. The museum says one of its aims is to "help to de-mystify homosexuality among people... we hope to reject the all too well known argument that homosexual behaviour is a crime against nature." Most of the exhibition is based on the works of Bruce Bagemihl and Joan Roughgarden.
