Cool.

An interesting and beautiful illustration. It would be nice to include some explanation of what exactly parameters n, a, b and c are controling.

Author's comments: for an explanation of the a, b, c, and n parameters, see "shellgui", also in the MATLAB Central Gallery.

Just as the sound of the sea flows through a seashell, the sound of love flows through the heart.
