...I stumbled upon a pretty interesting link on Tumblr (for once not nude chicks or dressed up pets). And given that SummerDave's next post is likely about music or perhaps the unveiling of a new song, this link seemed to fit as filler.
A Brazilian design student has created a product called Sound Track, "a mash-up that aims to teach kids how music works while it simultaneously teaches them motor skills." Now, I do not have children nor am I musically-inclined, but this seems pretty genius to me. Is this something you G:TB parents would get your kids?
