The Unicorn is a legendary creature embodied like a horse, but slender and with a single (spiral) horn growing out of its forehead. Unlike many mythical creatures they are generally depicted as gentile, friendly creatures who don't harm humans.  That is a little surprising given their horn which could obviously do some serious damage. Fresco in Palazzo Farnese, Rome, probably by Domenichino, ca 1602 The 'unicorn' cave painting from Lascaux. There is some speculation the unicorn legend came from the Narwhale which has a long spiral beak. Unicorns are popular in books; Anne McCaffrey had a whole series of science fantasy about Acorna, the unicorn girl.  Unicorns seem like they would lend themselves to some creative work with digital images.  Given a collection of horse pictures it should not be hard to make a unique horn and attached it to the appropriate place.  As in the picture above, it would also be possible to place this new unicorn onto a background picture, a photograph of a landscaped garden, or perhaps some other kind of nature picture.
