Long ago before there was 4chan, there was a website called 2channel. It was an anonomyous Japanese textboard that became one of the biggest internet communities in Japan. Because the textboard did not support image embedding, users created their own images out of text. This type of art is often called "ASCII Art" or "AA", but is more accurately referred to as "Shift_JIS art" or "SJIS art" due to using the Shift JIS character set (as well as a non fixed-width font).

Many of the AA images evolved over time to become popular memes, with characters such as Mona and Giko becoming comparable to wojaks or rage faces. Sadly, there currently isn't much of a community for them on the anglophone web.
