Music Mug by Masato Tokuno
Just how a coffee mug is great because you can bring your coffee with you anywhere you go, the music mug was deisgned to allow you to do the same thing with your personal soundtrack. Plug in your mp3 player, drop it in the cup, and your music will play out of the built in (hidden) speaker. Then, if you have to move around, your music can come with you! What a great idea.
