I still having fun with this of icon designing, I decided to practice with the iChat icon, the result is very close to the original one. Also I added a mod with the new twitter logo, and with a @.
I added some colours mods too. And yes, PSD is included, I think that it will be enough to make your own mods if you like to.
The rest info on the preview: ico, png and icns. from 16 px to 512 px.
Thanks in advance for favs, comments, watchs, etc...
