dd got to have a go at a Soundbeam today (for them what don't know, its a sensor that picks up movement and turns them into sounds)
It was pointed at her head. When it was turned on she spent about 5 seconds moving her head. Then she went absolutely still so there was silence. You could tell she was thinking. Then she made one head movement and got one note. Made a huge smile and deliberaly made music
We wants one now! Only 2 grand!
