Looking Ahead to Retrospectives

While there's no glossy coffee-table book in our foreseeable future, we are in fact running a series of retrospectives this year. The February issue featured CAD/ CAM/CAE highlights, whereas March covered gaming. In this issue, we look at digital milestones achieved in the making of television programs and commercials. Upcoming issues will feature science, architecture, and of course, movies.
