Blipblox is a deceptively simple-looking toy that lets young kids experiment with sound design and music.
Presales start this spring, according to the description:
The Blipblox is a fully functional synthesizer beatbox that has been simplified and optimized so everyone, including children as young as 3 years old, can enjoy synthesizer audio exploration. This video will give you a taste of the wide range of fun sounds you can create on the Blipblox. Ships with a Learning Toolbox to help older kids (and adults with no synth experience) dig a little deeper.
My personal policy is never to give children's gifts that make any kind of noise, but if there's someone in your life with a high tolerance for kid-produced sounds, maybe their little creative person would enjoy this.
