The details for the closed-form expression are in A closed form for Unitons.

A generalization of the construction to treat Ward's integrable Chiral model is described in Ward's Solitons. A Maple program to compute solutions, and some Quicktime movies of evolving energy densities are also available from the author's web page. The Quicktime movies were created using Richard Palais' wonderful 3D-Filmstrip Macintosh visualization program.
