The Doppler effect is that difference in sound you hear when a vehicle runs in your direction, and then away from you. It is a sort of echo of the soundwave.
This script will create that "wave" on top or on the bottom of any text you provide. You can use a solid color, a gradient or even a pattern. In the end, the main text and the "echo" will be on separate layers so you can apply different effects to it, separately.

The winner will be announced in the newsletter, next week. Not a subscriber yet? Not a problem. You can register here and it is free (and you only get one email per week).
As a sample, I ran the script on individual digits starting with a black text. This will allow you to colorize the elements to match your project. To maintain the transparency on these digits while adding color, lock the transparency of the layer, fill with the material you want, and unlock the transparency.
