I was very fond of using Flash to create animations, using either Flash or Xara's .swf export , it was so simple. But those days have gone. I've yet to find a decent html5 replacement that comes anywhere near as close as Flash re ease of use and file size. I currently use Hippani Animator 5.1 but it appears that this software has now fallen by the wayside too.

Obviously all graphics created using Xara.

Here's a nonsense animation created in Hippani , just fun creating animations, no particular rhyme nor reason
