So, you know how when you draw a picture on paper you use little dots to make up the picture? Well, when computers make pictures, they use the same idea, but they call it "pixels".
Raster-noton is a really cool company that creates art and music using these pixels. They use lots of different computer programs to make pictures and sounds that are super unique and interesting.
It's kind of like when you use different color markers to draw a picture, except they use different computer programs to make their art. They also sometimes use special machines and instruments to make sounds that go along with their pictures.
Overall, raster-noton is all about making cool art and music using computers and technology.
