Here are links to a few more of my logos, in case anyone wants to see a more representative sample.

This is a 3D-reverse-video version of the 'insignia' or 'sigil': http://img511.imageshack.us/img511/8684/sireversebrightmetal.png

This is my original lettering, which I was advised no one else would like: http://img209.imageshack.us/img209/1094/singularityinstitutemet.png

And here's a 'retro' one featuring the SI's 'old' name, with a rather subtle visual gag (is it subtler than the one in my last comment?): http://img200.imageshack.us/img200/1769/singularityinstitutefor.png

Needless to say, I can do any of the layouts with any of the letter forms and any of the surface treatments (and so could anyone else with three of my svg files and a rudimentary grasp of Inkscape).
