Secular Nirvana's logo should have a futuristic feel to it, but the word Nirvana was not chosen at random and it should be incorporated into the look and feel of the logo. Currently there are two versions of the logo I am considering and am currently open to both.
1) A futuristic/circuit bonsai tree can stand as the main logo, similar to the Discover Magazine cover I have attached. With bright and futuristic greens and/or blues this design can display both the emphasis on technology as well as the nature and zen like aspect of Nirvana. I attached some other examples.
2) A meditating robot, whether humorous or serious. I prefer the futuristic and clean look of the white robots attached in the image, the material of the character Eve from the movie Wall-E but I am open to what you can create if you feel you understand the vision.
The slogan Science, Happiness, Prosperity, and Humanism on the logo is definitely a plus, but if its to hard to fit I wont rule out a design because of it.
