Sprite moves and changes costumes based on your voice measured by your computer's microphone
Your computer needs a microphone to play this.
Hit the space bar.
If sound is above a certain level, the Cat sprite turns and changes color.
Else if sound is softer, the butterfly sprite just glides.
Please remix this anyway you want - change sprite, motion, volume level required to trigger the sprites spinning, background, add music.
Add another sprite and have it react to the volume (loudness) level as well.
Thanks to the Scratch team for the tutorial video that got me started.
