This xmas I bought my niece a Crayola ‘Colour me a Song’. It’s kind of reactive music for kids. This was the result :
The really interesting thing about her interaction with it was how much more she interacted with the visually interactive elements ( the lit buttons ). She really understood that things were being turned on and off very quickly. Connecting the more abstract concept of speeding up music with faster pen movement was somehow different. Perhaps as it required association with her movement and the tempo, whilst also being distracted by another wonderful and very visual thing – the crayon.
It made me think that when designing forms of reactive music I should avoid competing with things like crayons.
