MUSIC COMPOSER PROTOTYPE
While at Idbias, Lego approached my co-founder Joy Mountford to consult on a music construction set they were exploring. Joy had worked extensively on musical devices while at Interval Research. Our engagement with Lego consisted of building a series of virtual prototypes to demonstrate options given the Lego's design constraints.
I'm afraid the prototypes no longer work. But you can find the product on Amazon and eBay from time to time.
