Check out this website if you need to quickly create a sequence diagram to show to a colleague.  Just type in words what the sequence should look like and the web page auto updates with appropriate sequence.  You can even save you text and reload it back later and best of all save image and send to your colleague for further discussion.  This is great for those quick ideas and best all you can collaborate with friends on designs.
