I needed to build a simple Password Strength indicator much like the ones you find on google registration pages. Using some simple RegExp ( Regualar Expressions ) it wasn't that hard.
Below is a simple example that uses the class to display the security level as well as updating a HBox to show a visual indication of the quality of your password.
The crieteria for the regular expressions are to check Capital letters, standard letters, numbers and none word characters to build up the quality level Right click to view source

Ok so I was given the challenge of creating a TV style distortion effect for a project im working on. The obvious solution for this was to use a sound wave and create a distortion effect based on the SoundMixer.computeSpectrum( ); method in combination with a DisplacementMapFilter to build a distortion effect for any Sprite in an Application or indeed the application itself.
