The Javascript Raytracer has been expanded quite a bit since we last saw it... now you can even use it to build your own custom scenes (see the extensive Help-section).

I like Friedrich Lohmueller's abstract raytraced artworks... especially the Loops (with pov source files and tutorial).
Revisiting the snowflake theme, in POV-Ray. Source file here.
A random path of large and small cylinders, evenly rotated around the y-axis six times and mirrored to form a symmetrical snowflake.
Trying out texture options, I stumbled upon normal { facets size 2 }, which turns the smooth cylinders into these neat crystal-like shapes; makes me want to reach into the monitor and grab the whole thing, spin it around, feel its weight...
Past snowflake inspired experiments:
- DHTML snowflake generator
- Java-based snowflake generator
Continuing my self-imposed no-photos-for-one-week rule, I decided to rediscover POV-Ray (freeware raytracer) a bit. The current version has some features I never tried before, like isosurfaces (this rock is one).
It's still great fun simply placing objects, playing around with shapes/parameters and seeing what happens, especially now that I have a PC that can generate images like this in a couple of seconds. When I first tried POV-Ray ten years ago, scenes like this took two hours to render.

Downloaded a bunch of real-time raytracing demos off of this page. Ooh! Pretty! [via this thread on tweakers.net]
