Can you guess what this is a picture of? It is actually the Maths Inside logo, well part of it. I took a photo of the Maths Inside logo displayed on my computer screen with my microscope camera toy. It made it 50 times bigger! The little rectangles are called pixels. The monitor screen is made up of over 2 million pixels so this is just a small section of the whole picture. Each pixel is made of three even smaller red, blue, and green rectangles which light up in different amounts to make the colour we see. Rectangles are a good shape for pixels because they can fit together neatly without leaving gaps to form pretty colourful pictures.
