Abstract
Design environment for the computer has progressed recently. Digital contents on various areas are being created by tools incorporated new technologies. But mostly, the expressions are limited by a set of standard software and file format and designers can not break through the limit. I have explored "motlon" expression as possibillities beyond oi the standard format based on the traditional method of design. Because researches on dynamic characters of the computer as a media are few in contrast to the static side, such as tools for printings-computer as a paper. In this presentation, I propose a mechanism that allows designers to express a variety of motion on a computer screen.
