The site is a blog as well as a programmers portfolio. The blog will focus mainly on programming but it will also touch on living a healthy lifestyle, going to the gym, breaking nerdy stereotypes and so on.
I thought we could combine combine something programmers are familiar with (the uml class diagram) with something about a better lifestyle (the 'zen' japanese character). I have included a couple of crude mockups showing what I mean but they shouldn't necessarily impact the final design.
Obviously an entire class diagram would be too much for a logo, perhaps focus on a single class (uml class image).
