Wanted: Biopython favicon

Hi,

For the new Biopython homepage we are looking for a *favicon.ico* 
(that's the small icon that is displayed on the tab of your browser) 
which should look nice at a resolution of 16x16 pixels. The actual 
Biopython logo due to its banner-like format, doesn't seem to be a good 
template for this.

Please send your suggestions!

This issue is discussed on 
https://github.com/biopython/biopython.github.io/issues/86

In these two Stack Overflow questions you find some information 
regarding favicon sizes, graphic formats and more:
