intelligence using matchboxes. please welcome maisy mcadam and willow. applause. but possibly the most magical moment of all of our click live shows starred maisy and her dog willow. about six years ago at the age of 16, maisy was diagnosed with a brain tumour. over the next few months her vision was reduced to a tiny blurry circle in just her right eye. so if you want to pop those on to maisy now... well, maisy had agreed to try on stage the latest version of these givevision goggles. they use magnifiers and augmented reality to amplify the wearer's remaining vision and highlight outlines. maisy, are they working? yeah! i can see your microphone, and i can see that you are smiling and i can see the buttons on your shirt. take a look at the audience. yeah. they are waving!
