Ricky Martin explains what output devices are, including printers, earphones and televisions. He shows us the pixels on a television screen and explains that all the tiny squares put together make a picture. He creates a pixel picture of a ninja man using free art software, and meets a designer who uses pixel technology to create light-up clothes and bags that can display messages from Twitter. The designer helps him put his ninja man pixel picture on a skirt.

Using this clip as inspiration, children could design their own item of clothing or accessory that lights up using pixels. They could use squared paper to design the images they want to display or download free software to create a pixel picture.
