The BATSE Gamma-Ray Burst Data have been animated for display in galactic coordinates on an Aitoff-Hammer projection. For each burst the animation displays as a function of time both the intensity in Ph/cm$^{2}$-sec and the effective powerlaw spectral index in the energy range 50 - 300 KeV. Each burst flux history is displayed at its galactic location using a circular pattern whose radius is a function of intensity and whose color is a function of spectral index. A temporal compression algorithm has been applied to the data to render the burst durations' 5 order of magnitude range in a visually acceptable format. This method of presentation highlights may important burst characteristics including the diversity of flux histories, the considerable spectral variations within bursts, and their isotropic spatial distribution.
