Text Morphing Animation SVG
Here is a nice text animation that could be used for a title, or home animated element.
From the Author
This pen cleverly utilizes SVG filters to create a "Morphing Text" effect. Essentially, it layers 2 text elements on top of each other, and blurs them depending on which text element should be more visible. Once the blurring is applied, both texts are fed through a threshold filter together, which produces the "gooey" effect. Check the CSS - Comment the #container rule's filter out to see how the blurring works! Valgo
