Humans were always fascinated by fire!. I made this now in a bit less than 3 hours and I’m proud of myself! This is my first animated pixel (actually second, my first was a shitty running person).
Graphicsgale is a great program for this kind of work and I found out it works fine in Ubuntu using Wine (something I had often problems with). The free version doesn’t export to gif, but you can export a series of images and convert them from command line with imagemagick (example here: http://ubuntuforums.org/showthread.php?t=1034104) .
