The following technical information was copied from Greg Kilcup's Lattice Gauge Theory web page at Ohio State University:

This is a visualization of some of the first data to come off the new 128-node Cray T3E recently installed at NERSC (circa 1997). The still frames below show part of an eigenmode of the Dirac operator. Since we work in four dimensions the full structure cannot be shown in one picture; these images show single three dimensional slices. If your browser is Java-capable, click on one of the images below to animate the frames and see the full four-dimensional object as we loop over the supressed dimension.
