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!
The many ways a man may reach 50. A digital invitation in support of a matching card version for a Scottish Architect living in England at the time.
