The experimental observation of bright spatial solitons in the form of mighty morphing solitons is reported for the first time to the author's knowledge. These are Gaussian-like beams of elliptical cross section, which appear to change their shape constantly as they propagate. Saturation of the nonlinear medium is shown to progress logarithmically.
