> This "Publish > Feedback > Iterate > Repeat" loop doesn't just apply to smartphone apps, you can basically do this with anything in life, from hardware to mixology I again disagree. "Publish > Feedback > Iterate > Repeat" loop works when users can build on it from a previous reality that they can compare against. Physical demos that propose something that a user has no point of comparison with (new paradigm) you can either show a sketch/concept of what you want to do (to a tecnhical audience). Or build a semi-realistic demo to a non technical audience. Anything in between will probably be met with confusion or people focusing on details that are not the concept that you are showcasing.
