I just finished my conference report on Interacting With Immersive Worlds 2009 which was held at Brock. Keynotes included Espen Aarseth and Janet Murray, both of whom where interesting on narrative and games. Kevin Kee and I gave a dialogue on serious games which was well received.
Prezi – The zooming presentation editor is a neat PowerPoint alternative. You build a presentation that is one large map, then you script a tour that zooms in and out.

Prezi is also presented as a service where you craft and store the presentations online rather than through local software.
Springer has an interesting tool that lets you search for a pattern and see its distribution. When you search for a term it allows you to see distribution over time in the upper left, then distribution over disciplinary categories. It also shows a KWIC (Keyword in Context.)
