Transición de imagenes con silverlight 4.0

EL año pasado para ser más exactos a fines del mes de diciembre me encargaron hacer una postal con fondo de nieve y animación de imágenes en silverlight 4.0 y como aún no conocia las bondades del objeto DoubleAnimation pense en usar un objeto Timer... pero después me dí cuenta que no era una excelente idea, aquí les paso el siguiente ejemplo: http://cid-f11a91861874c761.office.live.com/self.aspx/.Public/SilverlightApplication2.rar
