ASCII art: n. The fine art of drawing diagrams using the ASCII character set (mainly `|', `-', `/', `\', and `+'). Also known as `character graphics' or `ASCII graphics'
This means that the images in this blog are not GIFs, JPEGs, AutoCAD blueprints, Lightwave renderings, or anything else of that nature. They're comprised entirely of characters you can type on a keyboard. It's an art form, albeit a strange one.
