I am interested in applying computer graphical techniques to

illuminate mathematical processes and objects. Ideally, this

can lead to a deeper understanding or at least to an increased

appreciation and awareness of the process or object.

Some of my projects are implemented as billions of particles,

others use the ray tracing technique and hundreds of millions

of rays. In either case, I do not use "canned" software,

preferring to write the code myself to first principles.

This image of helices coiled around other helices was an

exercise in recursive programming and parametric equations,

with a liberal use of tangent, normal, and binormal vectors

to specify finer and finer 'helices' beyond the original

true helix. It is hoped that the abuses of notation in the title

will be forgiven.
