Low pass filtering experiment...

I was trying to explore the realms of filtering, but didn't a get a neat way to get into it. Then one day, I thought about this eased sloshy movement that I always wanted to achieve when I used to make AVS visualisations in Winamp. If you don't know about AVS, check it up. It's one of the coolest Music Visualization System, and with a pretty steep learning curve. I learned to use that when I was 16 years old. Was a co-ordinate geometry buff at that time. There are some of my AVSes at deviantArt. If you have WinAmp with AVS, you can check them out.
It suddenly came to me that low pass filtering might just be able to produce an easing effect. And that was it. Processing came handy and I implemented a moving average filter where the dot co-ordinates are simply low-passed mouse co-ordinates.
Helped me visualizing filtering.
P.S. Processing is a nice neat programming language based on Java that can be used as a graphical programming language. If you haven't already did it, do check it out.
