American Sign Language Tutor

This program helps its user to learn American Sign Language. Using vector
graphics, it allows the player to look up the signs for various letters and
words; it can even read a text file on screen in ASL at variable speeds. Once
the user has studied sufficiently, the program offers a quiz mode where it
displays signs and requires the user to type in what they mean. The program is
quite configurable, even allowing the user to specify whether the signs
displayed on screen should be right- or left-handed.
