The WWW site for the Esperanto HyperCourse offers an introductory hypermedia course in Esperanto, an international constructed language. The course comes in a Hypercard format and asks users to point to an illustration of an object in a diagram to acquire its Esperanto translation. Translations of common words such as 'dog,' 'chair,' or 'table' are included in the course.
