Audacity

Audacity is a neat little free audio program. I first started using it to try to analyze student verbal responses via intonation and tone in a mathematics classroom. (It ended up not working out so well.) I later learned I could also use it to take mp3's and make ring tones. I had some fun with that. I pulled it up again today once I learned I could choose a sound file in my email client to alert me to new messages. How fun! I now hear a brief audio clip of "Mailman, Bring Me No More Blues" by The Beatles whenever I get a new message.

Let's see how long until I get sick of this.

My personal guess: 3 days.
