Four examples are shown which demonstrate the use of computer graphics to visualize chaotic attractors from EEGs (electroencephalograms). The recordings are made from multiple sites: factor analysis is used to partition the variance into orthogonal components, and the largest three serve best to represent the dynamics in the three Euclidean dimensions accessible using a flight simulator. It is then possible to observe the trajectories of attractors in 3-space, using color or time slices to suggest yet higher dimensions
