Nintendo 3DS Sound
If you haven’t already put music on your 3DS…
Do so now! Seriously, it’s a lot of fun. My favorite feature of Nintendo 3DS Sound is the ability to switch among several unique visualizations. (Helpful hint: some of these visualizations can be played.) There is also a control panel that allows you to manipulate the music by altering speed and pitch. Don’t expect the 3DS to replace your iPod, but this is definitely worth checking out...
