The gif shown is just a cropped preview - download the SVG and run in a web browser to see the real animation!
The magic effect, including tiny sparks (not very visible on the gif preview). Can be also used as a static resource as well - simply download the SVG and use at your leisure.
Fastest way to change the color is editing the file in a text editor and following the directions.
The animation is once again explained in the comments of the file - have fun!
As always, I would appreciate any input.
