What software did you use to make it?

I drew it, by hand, with Kolourpaint, on Linux, which,
according to Wikipedia, is a Microsoft-Paint like drawing app:

After drawing each line, I just saved the file to a new name,
e.g., drawing01.jpg, drawing02.jpg, drawing03.jpg, etc.

Then, I slapped it all together with this Linux command:
$ convert -delay 50 -loop 0 *.jpg animatedplans.gif

That created this:

The "loop 0" just means loop forever; and the delay is something
like 50 milliseconds between images, I think.

I use this method only because it's trivially simple to do,
so, I'm sure there are *better* ways to make animated drawings.

For example, on Windows, I'd just draw using "Paint.NET" or even
Microsoft Paint. Then, I'd slap it together using one of the
programs described he
