Web Presents Both Opportunity and Challenge for Comparing Data

Static Internet data was used in early Web browsers (before JAVA)

Old Web paradigm: use standard client-server HTTP Internet protocol best
suited for static HTML documents

user's Web browser <------ Internet ------> Web server 

     Steps:  1. Request for data           ===>
             2. Data returned from server  <===

Researchers can't easily interact with data, although could bring up derived static images
Internet is too slow to do real-time interactive processing from the Web server
Key question: How can we do real-time processing locally using data from both the
Internet and our local laboratory?
Solution: run graphical user interface (GUI) Flicker program on researcher's Web browser
