Mathematica 6 was launched on 1 May 2007. The new features include a possibility of interactively manipulating 2D or 3D images. Wolfram Research Inc. maintains a site, where more than 2700 such demonstrations (April 2008) are available (http://demonstrations.wolfram.com/), among them are my own 230 demonstrations, from which I introduce several major categories (http://demonstrations.wolfram.com/search.html?query=kabai&limit=20). The Mathematica codes can be downloaded and used with the free MathPlayer also.
