Audacity has had its current logo for a very long time (I found it myself about 8 years ago). I think it's overdue for an update, especially considering the current trend of flat, minimalistic UI.
With the help of this guy I made a new logo based on the current one. It's very Mac-oriented though, so I'll also be working on a new one in the meantime. While this one uses the awesome template provided here http://appicontemplate.com/osx
, version 2.0 will be a completely original design so stay tuned!
