I like the graphic in #266 a lot. I'd like to see this on a white background with the 6 and the "R" not attached. Also, a version with a different less bold font would be interesting.
I like #302 better than #303. I'd like to see the font be solid instead of an outline, with a closed P and R. Also move/resize the "Project 6 Research" so that it the same with as the P6R and directly underneath it. Then make the graphic a bit larger so that it is the same height as the text above it.
We really ike the icon in #309. We would still like the P and R close and the "Project 6 Research" moved/resized so that it is the same width as the P6R and directly underneath it. Then make the graphic a bit larger so that it is the same height as the text next to it.
