Whether you call it a tutorial, a workshop, or a class, we call it a course, and the SIGGRAPH 2002 Courses program is looking for all of these variations for the 29th International Conference on Computer Graphics and Interactive Techniques. Whether you submit a proposal or review submissions, you are invited to participate in the creation of the SIGGRAPH 2002 Courses program.     In an effort to accommodate flexibility in attendees' schedules, we are looking for proposals that emphasize modularity. Submissions should be packaged into 1.75-hour modules, so that on days when Courses overlap the other technical programs, break times will coincide.   The Courses program will be looking not only for modularity in its submissions, but also diversity of topic and delivery. Proposal topics might include: Art and science Research and application Hardware and software Hands-on and lecture Wired and wireless Education and industry Games and special effects Web graphics, design, and user interfaces The Courses program for SIGGRAPH 2002 will be utilizing both the Creative Applications Laboratory and, for the first time, the Studio, as venues for presentations. Courses of all lengths will be considered for the CAL, while only half-day and tutorials will be considered for the Studio. Courses, workshops, and tutorials will be offered in the CAL and Studio throughout the conference. The quality of the Courses program is up to all of us: submitters, reviewers, and attendees. Let's build a unique program that is rich in substance, diverse in topic, and flexible in presentation. Together, we can build a program that will enlighten thousands of our colleagues in the international computer graphics community.   VALERIE MILLER SIGGRAPH 2002 Courses Chair Georgia State University DEADLINE!
