Incredibox lets you create a band by combining beats, melodies, effects, a chorus and voices.
You start out with one guy who is seemingly naked. Then you choose one of the sounds, and drag it to the naked guy.
Poof! Once you drag the sound to the naked guy "clothes" appear on him and he starts his sound. A new naked guy will pop up.
Soon, you will have a band playing you very own original song.
Play around with Incredibox. Take out sounds and add new ones to create a whole new sound.
Beware, it is quite addicting. Hint, the beats make it sound awesome.
