'The Galloping Horses' mural stretches over 5 m X 1 m in oil on canvas, and is based on a series of photographs from a bronze naturalistic group of sculpted mustangs, galloping over an angular water area, within the minimalist futuristic urban scape of Dallas' city of Business, Texas, taken by Joyce while on a visit to her american relatives, in 2000.  

A number of small works, also on canvas, representing the same horses, albeit singled out and viewed from different perspectives can be found on 'The Horses Series: small paintings' page. A 2008 calendar which displayed them was released, as a limited edition of 15.
