While doing some background research on asemic writing & art, I found a glitch text generator and other related glitch information. ( unfortunately I found some of this after my son went back to London after his holiday visit, so I am trying figure out what some of the other applications are supposed to do). Played a bit with the generator and incorporated in this series of asemic compositions. The attempt is very prominent in first image.
Asemic writing falls between visual art and contextual text. We can look at asemic writing as an art form that uses the codes and conventions of calligraphy/typography. In this case, both meaning and emotional impact is derived from the form, colours, and textures(art medium used), rather than information communicated through the text. Because the text does not act as a direct medium of conveying a message, it is asemic, without meaning.
Contextual text refers to disrupting the linkage between words, phrases and graphics/symbols. By mixing random letters, words, phrases, and graphics meaning breaks down. Multiple fonts, writing modes, languages, and systems of symbols may be combined. Modifying space and direction will further disrupt conventional interpretation. Layering of text and mixing textures and colours will increase the disruption. In this way, the audience is forced to rely on personal context and associations to build an emotional & intellectual response out of an asemic assemblage .

While stumbling about the internet, I also found some other poetry and word-play text-generators at Language is a Virus. I also found a page from Revolvy that brings together many related topics concerning Asemic writing.
