Skitch is a great app with which you can easily and quickly share something with friends and do small picture editing.
It’s Mac OS only, and works perfect with the grapic interface, so it looks cool too. (It intergrates iSight seamlessly and you can also upload directly to Flickr, both of which I love.) 🙂
The image above is a still from a Heroes episode (2nd of season 2), and that show just ROCKS!
The actress is named Hayden Panettiere and she’s great in her role of Claire the Renerating Cheerleader.
