I was inspired by @mr-dang's use of SVG+XML to create images and have created this pulsating drop shadow example, which shows how vector graphic images could be dynamic rather than just static as they are created programmatically.
Honestly the amount of stuff we could do with SVG+XML encoding is limitless, I've already started incorporating it into my Apps. So, Thanks again to @mr-dang for spreading the knowledge!
I've separated the R/G/B/A and Path components in the code and given a page of examples.
Feel free to use the concept in any of your Apps or adapt is as you see fit. App is attached, comments are welcome!
