I just had some fun with designing
Today, most digital designs are vector graphics.
What is a vector graphic?
Great question! Think back to school, geometry, you learned about vectors... Nope? Or you just don't remember? Don't worry, let me break it down for you. 
Generally a vector is a mathematical statement, that connects two or more points in a specific direction. These points consist of coordinates within a two-, or three- dimensional room. 
Now, these vectors can create any shape you wish. Just like the designs shown above. However, what makes them special, is the fact that they're not actually lines drawn onto a surface. If exported with the correct format, vector graphics can be enlarged to any size without getting blurry or pixely. Vectors also allow you to create a transparent graphic!
Here you go : )
Some math that was actually useful after school.
