This paper discussed an idea of curriculum and the software project named Meta-toys. The first primary motivation of the curriculum was designed for learning way of media-art, but now the goal is more comprehensive for leading generic computer literacy. Through the workshop, students could learn not only how to use computer software, but also how to make software for works along with own independent needs. Using computer, we can create various kinds of art works including painting, music, and literature. In many cases, computer is used just as substitute article of traditional media like paper and ink. To touch more computer specific idea, it would be better to know about generalization. Meta-toys' workshop introduces the way of thinking about how to use computer effectively with making presentation tools. In addition to show the workshop, we describe necessary software features for the workshop. We had a workshop using Squeak etoys because all our students have not special knowledge about computer. Because current etoys is not enough for our purpose, we have developed miner upgrade of etoys rather than major rebuilding. Some of our results could be regard as prototype for new Squeak scripting system.
