Lyric Speaker
Visualizers, and even visualizers with lyrics, aren't anything new. They just require a computer. Or did, until now. When you play a song on the Lyric Speaker, it uses its built-in Wifi to look up the lyrics to the song and analyze its mood, displaying both the words and algorithmically-created motion graphics on its translucent LCD screen. Dual high-res drivers ensure your music sounds good, and Google Cast support means it plays nice with a host of other gadgets.
