This is my second rendering of the so called Mandelbub fractal object. It was oversampled, but I wanted to ensure the quality was there, so antialiasing and motion blur were pushed more than needed. However there are some artifacts there due to some math inaccuracies.

The rendering was done in regular C, in the CPU. It's multithreaded but not SIMD-ed. Render times were around few seconds per image (sub-frame). The surface detail is adjusted dynamically for every ray to ensure low computation cost and less aliasing.
