If you know algorithms well, create a visual simulator for algorithms. Take a user input and then display the results from each step of algorithm visually to people who want to learn algorithm. Most algorithm books show the steps with boxes etc, build them dynamically and displays the changes user input goes through during each step.

This would be awesome. One of my favourite articles of recent is http://bost.ocks.org/mike/algorithms/ which covers this kind of thing.
