How about an idea to pioneer for the 'Animated' screenshots?
Consumers, & in general Public are going more aggrieved day by day from their respective Governments & Corporates....!
Writing an email that incorporates an 'Animated' sceenshot(like a Booo..with an animated Thumbs Down) would help transverse the very expression, & hence an Outcome!
Also, along with the regular 'Clipart Objects', do introduce an 'Emoticon section' as well for yours Screenshot Captor.
I don't think that you're likely to get a better response through animated GIFs in emails. (That is the only possible animation in an email as no mail client supports anything else - those days were a disaster.) Or at least not when sending to government or corporations.
Affecting change is likely to be more effective when simply withdrawing financial support for government and corporations and getting as many people as you can to do the same, e.g. boycott McDonalds, boycott Monsanto products and manufacturers that use their poisons, etc. I'd get into that, but the thread is about animation...
It's likely more effective to record a video, then send a linked screenshot of it in your email. A YouTube screenshot or Vimeo screenshot is pretty distinctive, and people will know what they are.
GIF emoticons have been so badly used and abused over the years that they now have a very stale, sickening feel to them.
Another problem is that there are a lot of "smiley" emoticon companies that basically distribute spyware. Again, it sullies things.
It would likely be better to use some GIF animation software to create a custom message in an animated GIF, then put than in your email.
Now, I don't think this is particularly going to be effective, but, it's just a simple example:
It takes a few minutes, but it's not particularly hard.
