I'm so sorry. Adobe Flash is now well and truly retired (like me) and if you're a certain age I doubt you even know of it. It was the average person's way to build complex sound enabled interactive animated apps without having to be a coding geek. The downside was you needed a clumsy plugin to view them and the files could be big. Gone!
Geology Subduction (Flash)
A simple illustration of a geological process. It was part of a larger project in which the specialist terms are made clear and put in a larger context. There was no need to explain everything in this image.
Flash content does not work on mobile and you may have to download the Flashplayer plugin from Adobe to view it on your desktop browser - at the time of writing anyway - plus this tech might be entirely defunct by the time you're reading this - things move on.
