“Thus I floated, till something gently touched me. It was a little boat floating beside me. How it came there I could not tell; but it rose and sank on the waters, and kept touching me in its fall, as if with a human will to let me know that help was by me. It was a little gay-coloured boat, seemingly covered with glistering scales like those of a fish, all of brilliant rainbow hues. I scrambled into it, and lay down in the bottom, with a sense of exquisite repose. Then I drew over me a rich, heavy, purple cloth that was beside me; and, lying still, knew, by the sound of the waters, that my little bark was fleeting rapidly onwards.

“Finding, however, none of that stormy motion which the sea had manifested when I beheld it from the shore, I opened my eyes; and, looking first up, saw above me the deep violet sky of a warm southern night; and then, lifting my head, saw that I was sailing fast upon a summer sea, in the last border of a southern twilight. The aureole of the sun yet shot its longest rays above the horizon-waves, and withdrew them not. It was a perpetual twilight. The stars, great and earnest, like children's eyes, bent down lovingly towards the waters; and the reflected stars within seemed to float up, as if longing to meet their embraces. But when I looked down, a new wonder met my view. For, vaguely revealed beneath the wave, I floated above my whole Past. But so indistinct were the visions, that sometimes I thought I was sailing on a shallow sea, and that strange rocks and forests of sea-plants beguiled my eye, sufficiently to be transformed, by the magic of the phantasy, into well-known objects and regions.”

Down in the turquoise waters of the sea are ocean rocks hollowed by the waves into caves and grotesque shapes. Around them grows sea-weed and coral in every shade of the rainbow. The rays of sunlight shine the ripples of the surface down on the sandy floor littered with seashells and starfish. In the distance dolphins play around a diver against the background of giant kelp.

“I arrived at another hall, the roof of which was of a pale blue, spangled with constellations of silver stars, and supported by porphyry pillars of a paler red than ordinary. The whole of the floor of this hall, except a narrow path behind the pillars, paved with black, was hollowed into a huge basin, many feet deep, and filled with the purest, most liquid and radiant water. The bottom was paved with all kinds of refulgent stones, of every shape and hue. Led by an irresistible desire, I undressed, and plunged into the water. I rose to the surface, shook the water from my hair, and swam as in a rainbow, amid the coruscations of the gems below seen through the agitation caused by my motion. Then, with open eyes, I dived, and swam beneath the surface. And here was a new wonder. For the basin, thus beheld, appeared to extend on all sides like a sea, with here and there groups as of ocean rocks, hollowed by ceaseless billows into wondrous caves and grotesque pinnacles. Around the caves grew sea-weeds of all hues, and the corals glowed between. I thought I had been enchanted; and that when I rose to the surface, I should find myself miles from land, swimming alone upon a heaving sea; but when my eyes emerged from the waters, I saw above me the blue spangled vault, and the red pillars around.”

This fractal created in Apophysis turned out looking like some very brightly-colored coral. I added the gold framing and gem in Paint Shop Pro.
