In Greek mythology, Helios was the God of the Sun that was supposed to pull the sun across the sky in a fiery chariot that was pulled by two horses (if my mythology is a little rusty, please correct me, but nicely ^_^). This is supposed to be one of the horses. The three circles will eventually be the sun rising, at noon, and setting. The vague stripes will be niftily faded sky phasing through all the colors that occur during the day (deep red near the bottom, deep blue at the top). The mane and tail are just really elaborate flames. My horse anatomy isn't the best, but I'm particularly proud of this because it actually resembles a horse.
