Embedding a fingerprint onto a familiar water drop symbol perfectly stamps the idea of human beings having a mark on the future of the handling of water resources. The simplicity of the design and the calming blue culminate in an effective logo.
Here is another example of a simple stylization of a logotype. The "A" in Water has a water droplet replacing one of the stems from the letter. A good modern logotype who's symbolism is easily identified.
Love the simple illustrated water and geometric shape. It's got depth as well, as you start to realize that the simple hexagon is a shape//// I like the water like effect that's around the floating bolder.
