I was already writing and showing how to embed Flash animations in a SharePoint Blog or any Enhanced Rich Text Field.
Watching MIke Gannotti's video about what I was already presenting he had a good point, the solution is not so user-friendly.
So I changed the methodology a bit. Now the simple-to-deploy solution offers the following features:1. Embed almost any HTML code snippet
2. Additional button in the Rich Text Toolbar to help you embed
3. A User Interface for pasting the code snippet
The deployment instructions are on the homepage and in the release zip file.
