There are a few more constructed (artificial) languages you might find interesting. 

Esperanto, Klingon, Lojban, Toki Pona, Volapük, and Interlingua are the most well known examples of such languages. 

International auxiliary languages (IAL) are languages constructed to provide easy, fast, and/or improved communication among all human beings, or a significant portion, without necessarily replacing native languages.
