In an article at eWeek, Ward Cunningham (developer of the wiki) said, "he has been interested in taking long-term looks at 'how wisdom is collected in organizations, … especially the wikiwiki Web style of talking about experiences, and the way that large groups of people can communicate'." Cunningham sees the development of open source (freely available to all) software as just beginning and sure to grow, " and it's not just because of cost, but because of end-user innovation." I'm guessing that Cunningham is right about the end-user innovation moving software forward to the benefit of all. It definitely benefits innovative teachers and curious kids!
Meantime, there are some excellent little programs for younger students at Sen Teacher Resources. This is a British site, so the instructional pieces around money won't work for American students. But lots of the materials are right on the mark! And for fun, be sure to look at these optical illusions. This is a PowerPoint show, so click "open" when asked.

The illusions are great. I used them as a warmup with my students. The kids loved them, then had a great discussion about what caused each illusion.
