run a peice of medium to fine sand paper accross it once (any direction, one straight stroke) try it (you should notice a two point starburst)
now run the sandpaper across it again at 90 degrees from the first stroke. (you now have a four point startburst) you can do six or eight points like that, each swipe with the sandpaper will also cause more diffusion and soften your image.
the effect works on all point lightsources (try a candle in a dark room for example).
