Leal Audirac has developed a particular type of transportable frescoes on double-curved synthetic surfaces which constitute a fragment of an imaginary architectural space.

Based on the executive plans of the Tramontana car and of a yacht, he developed a series of mathematical sculptures, like The Golden Sea and Touch me that change color with light and the spectator's movements, shimmering from purple to cobalt blue and from gold to green.
