MuseScore

MuseScore

It’s like Microsoft Word but for music.  MuseScore is great for either writing your own music or it can be used to create piano tracks.  I have used it extensively to turn choir music into practice tracks for each part. For example, I can make an mp3 with the Soprano 2 part playing loud with the rest of the notes in the background. This allows whoever is singing Soprano2 to listen to and learn their part.

Google Maps

Google Maps

While creating a map to show a single location in Google maps is easy, when you want to show many locations on a single map things get more difficult.  Using Google Maps API allow you to show data in a new and interesting way.
