My blog Embodied Universe sits at the intersection of psychology and cosmology. It leans towards being scientific, while also speculating about the future, for example, the singularity and beyond. It strives to do this while being as rational as possible (see http://lesswrong.com for what I mean by rational).
More about the blog:
"Embodied cognition" refers to a theory in cognitive science that you can't have a disembodied intelligence. Indeed, that our intelligence is derived from our physical interactions with the world, via our body.
For example, various studies in the field of embodied cognition have demonstrated that when you use a tool such as a hammer your brain represents the hammer as an extension of your arm. And that when you drive a car your brain represents the car as an extension of your body. Now imagine that, through the apparently impending technological singularity, you gain control over vast quantities of matter. Indeed, imagine that the entire universe is represented in your mind as an extension of your body and that you actually have control over it.
Let's go further. It might be hard to tie this all together, but that's ok. Hold your breath for this part: Various religions have a concept of the not-self. In Christianity it is union with God. In Hinduism it is the concept of embodied reality. In Buddhism it is Nirvana. In clinical psychology it is a disorder known as depersonalization. What the east strives for through meditation, the west calls psychosis.Recently, brain scanning studies have shown that this not-self state of consciousness can be induced by taking psilocybin (mushrooms), in which the default network, which supports introspection, and the task positive network, which supports your interactions with the world, become correlated. You lose your sense of self and feel like you are one with everything.
The union of what I've described is the motivation for the banner I would like for my blog, Embodied Universe. You not only feel like one with everything, but you ARE everything. Note that I am not saying that this is true, but that it is a conceivable possibility, and it is a direction I am interested in considering on this blog.
Here is some example artwork. You are free to use any background work so long as it is freely licensed, especially if it is from NASA (which is public domain).
This is similar to what I envisioned in that there is a thinker emanating from the big bang. However, the thinker might be a brain, looking forward into a singularity (for example). He could have eyes and arms. That's somewhat creepy though.
This is an image of a technological singularity (and a black hole). I imagine that throughout the universe there are many of these happening right about now, going forward in time, and that they ultimately become black holes that are interconnected via wormholes. This black hole network is like a neural network, and it is a universal superintelligence.
This is the classic image of the history of the universe:

This is interesting:
You might also search Google Images for 'fmri' and 'fmri universe'. Incorporating high contrast fmri-style brain scans somehow would be awesome.
In order to tie all of this together, consider that I (sometimes) feel like I am not a self, but that I am just reality. When I look at the night sky I am looking back onto my own past. When I look forward in time, in my mind, I see a technological singularity which may culminate in the creation of a black hole. And I wonder if I am entering a network of black holes, gravitationally connected via wormholes into the superintelligence that is reality.
You have complete creative license, except please keep in mind that I prefer a black themed blog with lighter text. If you can manage to fit a very small version of your signature with your url below it in the bottom right, that is acceptable.
