Connect-a-sketch is a new (beta) site for taking sketches/images and then creating a flow chart out of them. This can be done by uploading an image and then creating links to tie everything together into one smooth flowchart. Also, Connect-a-sketch has a nice user interface that is all drag-n-drop which makes it ideal for users.
