The ibex is a type of wild goat in which males often sport incredibly long, curved horns. Ibex motifs can be found on a variety of ancient artifacts, and it's believed that the horns of the ibex were once used as a childbearing charm.
Intrepid Ibex, meanwhile, was released October 2008 and added several improvements geared toward mobile computing and desktop scalability.
