Gimp is great!
Gimp is open source.
What is Gimp? It edits image files. It has loads of filters and tools. One really good one that we show today is the Filter->Decor->Old Photo… which uses sepia toning (if you are into photography in darkrooms, you may remember some chemicals to do this) to create the effect of an ordinary photograph with apt subject matter, turning into an old photograph that has been in a photograph album for a looooooooong time.
The tutorial today was created using the brilliant Gifpal, a web application making it pretty easy to create an animated GIF.
