Create this easy Glass Displacement effect in Photoshop! Add a rectangle and switch the fill to gradient, set the angle to 0 degrees, and duplicate to fill the screen. You can create unusual displacements by adding twirl or zig-zag to the pattern, or flip it. Save as a Photoshop file. Add your content and go to Filter Gallery. Select Distort, Glass, and use a texture - a manual one or the one of those you saved. You can customize it to fit your content, and then add a gradient map. Your glass displacement effect is ready!
