nmap.org has trawled the top 1 million sites on the web to collect all their favicons and put them in this great poster.
Each favicon is presented at a size relative to its rank (using Alexa).
There we are, right down in the bottom left of the poster!!! Its our previous favicon before the rebrand but it still counts!
Check if you favourite site is in there by using the search engine at http://nmap.org/favicon.
