Technology I'm liking right now

So, as I've mentioned in an earlier post, I did some exploring of technologies I might be able to use in my classes. I already have an interactive white board and I make extensive use of that. So in addition to numerous sites I love specifically for their frenchiness, here are some online tech tools I'm planning on using this year:

1. http://www.wordle.net : allows users to create word clouds. I see this working both for giving students a chance to practice with specific functions (like describing themselves) and as a really cool tool for analyzing literature. Downside: no way to search for created images once they're uploaded to the gallery and the process for saving them to a computer is a bit tedious as well.
2. http://lingtlanguage.com/nnaditz allows me to create my own speaking and listening practice activities, using my own voice or using video that has been uploaded to youtube. I've created a few simple activities so far, but I'm planning on creating more and expanding on the creativity of how I use the program.
3. http://manyeyes.alphaworks.ibm.com/manyeyes/ allows users to create many different types of analyses based on data sets. I haven't figured out how to use this yet, but I have a feeling it could be really good.
4. http://wiki.classroom20.com/ has an awesome collection of links on the use of Web 2.0 technologies in the classroom
