This might be veering towards narcissistic, but as I had downloaded an animated GIF creation package the other day, I decided to try it out.
The picture below is the first result of my learning the basics.
The filename tells you all you need to know - ChrisOver12YearsResized.gif
OK, the resized bit is irrelevant (I was working at around 800×600 originally, and so had a HUUGE file in terms of kilobytes)

The file is still just under 200Kb, so apologies to anyone else on dial-up access to the internet.

[edit] Thinking about it, it was probably over the last 10 years, not 12…
