Earth Language Project P&L: -6 (≃ -53 EUR)
Earth Language project, is a project conceived of by Yoshiko McFarland, as a result of the times of war between Japan and the U.S., inspired by harmony in nature, the hope for a more peaceful world. Inspired by the success of Chinese characters, and also, by their limitations (being not culturally neutral, and not compatible with a variety of languages of different types), she came up with characters that would be truly culturally neutral, and work well trans-lingually.
Think of it, as an attempt at creating an "esperanto" of the pictographic language. However, the language also has a phonetic code, that is based on the shapes of tongue, as expressed by the geometry of the characters, that can also be used as sign-language through hand-signing. EL works not just as a communication tool, but also as a thinking and imagining tool to explore one's self through the philosophy behind the base symbols of the language.
Other contributors, notably Jo Chen (German), Tomotake Fujita, Mr. Mitsuhiro Saiji, volunteered to create EL-ASCII (zero-width space ASCII font) for typing the characters, allowing to actually use the language in the Internet.
Many other challenges remain, if we wan to have this language learned and used. ^__^
