Click the green flag and watch. When it switches to the next text sample, change the sliders and click the green flag again.
This remix uses a totally different approach than the original project by @RobFarley74. It looks good, but is much less versatile. In the original project, you could add any text with any font, and the effect would be applied to that, using the pen. Here, I made text cutouts using Illustrator, and simply moves a gradient sprite under the text. Since the text was converted to vector graphics when making the cutouts, you cannot edit the text.
