render 3 frames (gif images) in gimp: 1 of each star colour. if gimp has options for gif file save, then save as 87a (compuserve gif) and not 89a (transparent gif). open gifbuilder and all windows in gifbuilder. add frames to gifbuilder - they should appear in the list in the frame window on the left. then use one of the dissolve functions. perhaps 4 frames per dissolve. there are no layers in gifbuilder, as there are in photoshop and possibly gimp. one other rumour I heard was that gifbuilder doesn't work too good in tiger. it works better in OS 9 and jaguar IMVHO.
