Cluster

We have created a technology that brings together the best Websites for a specific topic.  The name of the product is simply called "Cluster".
I would like a simple symbol that portrays websites coming together (maybe mouse arrows?).  Since there are "clusters" of stars perhaps having stars coming together would work.  These are only ideas, the most important aspect is conveying to the viewer the concept of "convergence" or bringing together.

- Logo should/could have any of these attributes: powerful but hip, techy but cool. Maybe even a hint of an astronomy feel.
- A logo that looks strong but very simple.
- I kinda like the logo for Google Desktop: http://static.wakoopa.com/images/so…icture.png
- Maybe objects in a "swirl"
- Web 2.0ish might work.
- The logo/symbol should look good at a much smaller size.
- Symbol will be used as a favicon.
- Deliverables: psd and/or png file; font file

- Nothing that looks too busy with a lot of detail.
- Nothing too fun or goofy.
- Don't mind it having an astronomy or space feel, but nothing that looks like it's straight out of Star Trek or Battle Star Galactica.
