The new version, now enable to change the color of the particle depending of the built-in microphone volume input. That means that the color of the heart will now change to another color depending on how loud you speak into the microphone. The sound-to-size is still enabled, so now when you speak into the microphone, it will not only change color, but size too. Flurry Heart has a installation package that will help you install the screensaver properly in a few short steps, so you won't have to do it manually.
