The configuration software archive on my website has a settings file included. It is based on what I did for DCFAN and makes those lights more "blinky". You could try playing with the delay setting, which controls how long the board waits between each step in brightness, but what I did was a bit different. It changes the ramp shape to be more steep in the middle range. This means it will go through a bigger swing for quick brightness changes (blinking), but still take the same amount of time to go through the full range.
