I agree with Tufte's general point that the problem with all slide based presentation tools is low information resolution.<p><a href="http://www.edwardtufte.com/tufte/powerpoint" rel="nofollow">http://www.edwardtufte.com/tufte/powerpoint</a><p><a href="http://www.wired.com/wired/archive/11.09/ppt2.html" rel="nofollow">http://www.wired.com/wired/archive/11.09/ppt2.html</a><p>Some presentation suggestions can be found here:<p><a href="http://www.edwardtufte.com/bboard/q-and-a-fetch-msg?msg_id=00001B" rel="nofollow">http://www.edwardtufte.com/bboard/q-and-a-fetch-msg?msg_id=0...</a><p>I tend to only put figures and equations with the necessary explanatory notes in my presentations and discuss the rest. But creating paper handouts as Tufte usually suggests would still probably be more effective, since your audience has something physical to take home.<p>I think a mind map presentation tool with <i>infinite</i> zoom and pan could be an interesting presentation tool. Something like a high-resolution poster that you navigate in a presentation. It could be distracting to the presenter though.
