A fractal-based volumetric object. Available in the following versions:

RAW data 400x400x400 8-bit (zipped)

PNG codec AVI 400x400x400

PLY isosurface mesh 1.9M polygons

STL isosurface mesh (reduced) 956K polygons

This is from my series of volumetric objects created to help people explore the differences between polygonal and volumetric representations of objects.
