Super job! I love the animation. I thought maybe you had the animation version of UF, but I see you did it in another program. Have you tried GIMP? It can do basic animation and it also has the GAP (GIMP Animation Package) add-in that has a lot of power, but is not the most user-friendly animation program I've seen. But the GIMP basic animation is pretty easy and will usually accomplish simple animation tasks. But, I love this. Fun to look at!
Thank you very much, I'm glad you like!!! Yes, thank you Peggi, I use Gimp, but my UltraFractal gives the images with animation in extension avi, I needed a convertor of files avi to gif, because dArt doesn't admit files avi of more than 80 Mb. I just found Microsoft GIF Animator as gratuitous convertor.
