I put most of my photos up on Flickr under the Creative Commons license because I want people to see them and use them freely for non-commercial purposes. A few months back, I got a message on Flickr from someone at MIT who wanted to use one of my photos in one of their open courses. Today, I found a new message informing me know that the course has been posted along with my photo.

You can read the course yourself at:
