This work, Paris Metro Art, was created by Antoine+Manuel. Check out their site for more cool mural art.

Implications - Antoine+Manuel really have a lot of fun with bright floral lines and colors in this quirky mural, and there is something impressively whimsical about their work. Residents of Paris will arguably be among those who enjoy this creative work the most. By playfully reinterpreting the city's metro grid, Antoine+Manuel dramatically reinterpret the look and feel of public transportation like never before. In fact, it would be really interesting to see this kind of artwork become officially adopted by major cities around the globe. It would certainly make riding the subway a little more fun.
