Reactive Animations

The vocabulary used to create and manipulate graphic animations remains hopelessly low-level and focused on presentation. Conal Elliott presents a higher-level approach that uses functional programming to model behaviors and abstract and simplify the task of constructing animations.

Conal is a member of the Microsoft Research Graphics Group. His article, "Composing Reactive Animations", appears in the July 1998 DDJ and is also reproduced here.

Unfortunately, the audio recording of our conversation with Conal was damaged and cannot be used to obtain a transcript. As a result, there will be no transcript of this program. This is unfortunate but the encoded audio/video streams lives on... Enjoy. Also Conal's site offers a wealth of information on his activities as well as links to related resources.
