I’ve wanted to do this effect for some time now. It consists of one or more lines of text with variable indentation, and seemingly ever-repeating washed out copies of the text on both sides running off screen.
Decided to use text-shadow to implement it, though support is not as broad as I’d like to see. The primary pain in this is with the offset for the text-shadows. Due to the varying length of each line, you have to provide specific offsets for each line having the effect. This could a lot less painful if it were to be built with a preprocessor.
One really neat side-effect of this approach is that because it uses shadows, it inherently gives off a responsive feel; in the demos above you can see that it extends as far left and right as its parent permits.
