Learn to play the LED way! Learning to play a new instrument is hard—most of us have given up on a few—but Fretlight has designed a solution that gives beginning guitarists the lessons they need without all the frustration. The built in LED system removes the finger position guesswork new players struggle with by showing where the hands should be right on the fretboard. The $300 FG-507 Acoustic model is great for beginners, but novice rock stars should also have a look at the $600 FG-521 Traditional Electric model pictured here. If you want to go really crazy, Fretlight also sells a $900 Pro Electric model, but at that level of investment, we're guessing you have some idea how to play already.

They're not just cat ears—they can read your mind! Expressing emotions is hard (why not just bottle them up?), but the Necomimi makes it easy! Just put it on your head and let the ears do the talking—your brainwaves make them move! Believe it or not, it works! We're pretty sure, at least—if all is operable, concentrate to make the ears rise, and relax to let them lie down. When you do both at the same time, they move back and forth. Science!
