A very nice transition from Rob Gonsalves. The image starts on the left with a ship floating in a wavy ocean, the sails down. Further to the right the wind starts to set and the ship start sailing, apparently also transforming. On the right, the transformation is complete. The baffled spectator sees a seventeenth-century galleon sailing above his path in the middle of the desert.
In this beautiful painting, a breaking wave changes into horses galopping out of the sea.
