Pixel art is like painting with tiny squares. Imagine you have a piece of paper with tiny little squares all over it. Each square is called a pixel. You can color each pixel to create a picture. It's like a puzzle, but instead of putting the pieces together, you make the picture by coloring each square.
Pixel art is often used in video games and computer graphics because it can create cool and nostalgic looking graphics. It's also a fun activity that people can do on their computer or with special programs on their phone.
So, pixel art is like painting with tiny squares to create a picture, and it's often used in video games and computer graphics.
