I've been having fun with icons on Twitter, mixing things up, same way I put images in the right margin of Scripting News.
Peter Rojas of gdgt had an interesting idea. Why not start a feed of the icons. Indeed. :-)
I can't add something to the feed without it going out to all my followers, so I'm not going to put the old icons in there. For that, here's a zip archive.
And if I forget to put an icon in the flow, please don't be pissed, just remind me. :-)
