My compliments to the artist. Louisville's Red7e is the marketing firm for the upcoming World Equestrian Games in 2010, but in the meantime, they created a logo for the University of Louisville's Kentucky Equine Summit, to be held in Lexington April 28-29, 2008.
At first glance, it looks like a snowflake, a star or a flower, but look closer, squint!; it's a horseshoe mandela.
