TL;DR: The goal is to make simple animationremely easy to add to an interface, and still supportcomplex animations by providing better modularity for the software for user interfaces, and achieves increased reuse and decreased code size, and makes it easier for research-ers and developers to create applications.

TL;DR: The most important lessons are that mark-sweep algorithms are more efficient than topological ordering algorithms; lazy and eager evaluators deliver roughly comparable performance for most applications; and constraint satisfaction algorithms have more than adequate speed, except that the storage required by these algorithms can be problematic.

TL;DR: The important innovations in the Amulet object and constraint systems are the automatic management of a part-owner hierarchy in addition to the prototype instance hierarchy, the support for multiple constraint solvers at the same time, control over slot inheritance, flexible demons, and a convenient integration of the models with C++ without requiring a pre-processor.

TL;DR: Amulet is a new user interface software environment for C++ to support future userinterface software research and will provide sufficient performance, robustness and documentation so it will be useful for forgeneral user interface developers.
