Physics teachers have long employed video clips to study moving objects in their classrooms and instructional labs. A number of approaches exist, both free and commercial, for tracking the coordinates of a point using video. The main characteristics of the method described in this paper are: it is simple to use; coordinates can be tracked using any standard Internet navigator; it can be used with examples available on our webserver or with a modified example in the user's own computer; the web pages with new sequences of images are easy to upload to a web server; it is possible to track and analyze any complex one- or two-dimensional motion of objects; and the code is open source. The setup is very simple, intuitive, and can easily be scaled up.
