This is a cool text effect – it is a classic, and I’m not taking credit for inventing it, but I have written the entire class myself and optimized it for performance and the opportunity to change the text to Uppercase or Lowercase.
The speed of the shuffle is decided by the framerate, the example above uses 40 fps.
Have fun with it, it is all well commented and easy to use – I prefer to use it on small buttons etc. (it is not cool on large texts!)
This is an Actionscript 3.0 file – the shuffle is written as a class.
