Logo Proposal
What we had before was this as a rough sketch:

Then, we decided to use this font:

Now, we have these sketches:
A

B

C

I prefer the style of the letter "B" in version B above with slightly larger
cooling frames and a modified version of the octagon/vertex from version C.
Please send comments on the following features to gsfs@mit.edu:
- "OBO" slanting (as shown) or horizontal (as in original).
- Slash through "OBO".
- "P" larger than other letters.
- "P" 'shadowing' of "H".
- Style of cooling frames in "B".
- Style of 'octagon/vertex' outside "B" (I want to modify it a bit).
- Other features?
