People, who know Asian style hieroglyphs, might be able to get by without logos, but Latin script and Cyrillic script based words take up so much space that there is a practical need for some hieroglyph like solution. Since I (Martin Vahi) do not know any East-Asian languages, I tried to come up with something that

• fits to a square area, id est it fits well to buttons and checklists;
• can be rendered recognizably in very small resolution;
  
• is defined by a drawing algorithm;
• does not have a strong historical meaning like the Swastika or the red star;
• can be drawn understandably by using only 2 colors;
• (hopefully) does not have any connotations to classical religions;
• (hopefully) does not have any sexual connotations;
• (hopefully) does not have any classically derogatory connotations;
• (hopefully) is meaningless in all East-Asian languages;
• tries to reference the letters S and T from the compound word "Silk-torrent";
