Ethiopian-born, Wosene Worke Kosrof's language based paintings work so well because of what they don't say. It's obvious that we're not going to understand the language, if there is one, but our eyes still search for clues, for some sort of meaning in this jungle of characters. Using signs and letters as props in his compositions, he tends to drift between calligraphy, graffiti and cubism. Some works are all about the letters and others are more about color and movement. The top image, from Artnet (with no information) is even more different.
This image is from his 2006, Trans/Forms Exhibit at the Skoto Gallery. Viewing the 21 images from that show gives a good overview of his work. Also worth a look, are some images from his Shows in 2004 and 2002.
Avisit to his Web Site sheds even more light on his oeuvre.
