Tux Machines (TM)-specific
It's all well and good that Adobe did get the Flash plug-in for Firefox/Linux going, but what we don't (and perhaps will never) have is an Adobe-supported way to create Flash animations on a Linux box.
So we have Open Source work-arounds, and I'll be exploring them one at a time. After all, those of us who earn our living with a Linux machine could stand to beef up our resumes, right?
Here's a package to get started with: Get the SWFTools package. Let's check out the "brute force" method first, with "PNG2SWF".
I made a series of .png images of a simple vector star in Inkscape, saving them as "star_01.png, star_02.png" etc. When starting a sequence of pictures like this, it's best to name the files with zero-indexing; if I used "star_1, start_2", then when I got to "star_10", the file system would sort 10 between 1 and 2, which isn't what we want.
