Bomani, Eunice, and Matt have created a project called\u00a0Waves<\/em> which allows you to see the spoken word in printed form. A set of colour-coded questions is posed and you are then invited to answer them whilst pressing a colour-coded button. The appropriate question and your response are then printed out using a thermal printer – the question as text and your response as a sound wave (pictured above). You can read how they did it, and perhaps create your own, by viewing more about the project over at GitHub<\/a>\u00a0and see it in action below.<\/p>\n
