Incredibox has been around since 2009 which is a very long time in internet years! Incredibox can be used on your desktop or iOS device to create mixes of instruments, percussion, voices, and a variety of effects to create a unique mix.
This app is very easy to use. Select which version you wish to use then drag icons from the bar and drop them on top of the shirtless guy. You can add up to seven elements to your mix. There is an option to record your mix as well.
Applications for Education
This app can be used to introduce students to different rhythms. It can also be used by students to create raps that are based on different content areas. Imagine how much fun students would have writing a rap about the Constitution or some other topic. Students could even capture their rap and mix by using a screencasting app.
