Pillows
A simple wada fractal but illuminated from the centre and glowing (so popular these days). By applying ambient light we see circles representing the spheres themselves. POVray seems to only support 256 trace level (v3.6.1), not 1024 as when some of previous wada images (on Pauls pages) were produced. Careful tuning of light and materials is necessary to get good images revealing detail. A lot of bytes went on these.
