The Hills Are Alive with the Sound of Interaction Design
The first two of these already exist. And I’m happy I live in a world where I can use the phrase ‘music-eating electronic pet.’
The second two are products I’ve suggested which are a little bit silly but well within the grasp of Jack and me to build.

The interactions will be scaled back from what I’ve outlined here, but the products are fundamentally the same.
