As I mentioned in my last post, I have uploaded the Animated Activity Designer for use in your own project. A common question I can anticipate being asked is "Why?". So, here's why I created it and my reason as to why you may want to use something like this.
First off, the reason I wanted to try to created animated activities within the Windows Workflow designer was merely to see if it was possible. I knew that I could override OnPaint so I pretty much already knew it was going to be possible (otherwise I probably wouldn't have gone down the path). The second reason is simply because as a guy that loves cool eye candy in UI's, I just had to do it.
So why would you ever want to create an animated activity? Let's say you create an application that hosts the Windows Workflow Designer. Let's also assume that this application is used by your customers. You present them with the designer surface and within a Toolbox like panel, you have your set of custom activities they can use. If pictures are worth a thousand words, then an animation with 10 frames is worth 10,000 words.
The actual code for this is really simple which is also why it only took a couple of hours to get it up and running. Since it is so easy, I won't waste your time explaining it (but feel free to ping me if you have any questions).

To see it in action, open the solution in Visual Studio, build it and then open workflow1.cs in the designer.

P.S. The activities you see in the project and in the video are simply placeholders. They do not actually do anything.
