The first two I made myself in Microsoft Word.

Dot logo: simple! 3x3 dot array might work for 16x16 icon


Red oval: simple. Web site mockeup is here.


The following are the result of a collaboration of me and Reb. The 'Earth in a cage' suggests both a global network of computers, and an atom (i.e., science). The original icon came from Cryo64: http://www.cryo64.com/
Pearl, red gradient


Pearl, blue gradient


Earth, lowercase, blue


Earth, lower case, blue, no shadow


Earth/modern/gray


Earth, lowercase, copper, large cage


Earth, uppercase, copper, large cage


Earth, uppercase, separate earth with small cage (to be replaced with large cage)


Earth, uppercase, copper, small cage


Copper text (to be put below a copper logo)


Earth and medium cage only (could use as a 32x32 icon)


Black background (for screensaver):
