Google Voice is another Google product currently in preview. Google Voice might just revolutionize phone and voice mail. With google voice, you get a phone number that you could essentially use as your only phone number in the (near) future. Essentially, you can forward calls from the google voice number to any number you like and even change what number it is forwarded to based on the time. In other words, you can forward calls during the day to your work phone, in the afternoon to your cell phone, and in the evening to your home phone. You can even have the phone ring on all these numbers at all times if you like. Furthermore, you can set different numbers to ring to a different phone (i.e. friends always go to cell phone, work contacts always go to the work phone, etc.). As if that weren't enough...you can even set custom outgoing messages based on who (or what group) is calling. And there's more!!! Voicemails that come in are transcribed as text and can be delivered via email or sms.

Wordle is a toy for generating "word clouds" from text that you provide. The clouds give greater prominence to words that appear more frequently in the source text. You can tweak your clouds with different fonts, layouts, and color schemes. The images you create with Wordle are yours to use however you like. You can print them out, or save them to the Wordle gallery to share with your friends.

I have used this before and it is great. I posted it for a while as the "wordle of the day" on our web site.

a real time, live text collaboration tool. You invite others to join you (via email) and whatever they type will show up on the document (in real time) in another color. You can import a document into Type With Me, and edit it there in the space, live. You can save your document, export it, and even play it back (as if it were a movie) using a feature on the site called "timeline". There is also a chat area, so that you can have sidebar conversations with the people sharing your workspace that you might not want to appear in the document.

Open Cobalt Alpha is the first step in a long term project to make available to all people a free and open source platform for constructing, accessing, and sharing virtual workspaces for research and education. This 3D multimedia wiki technology makes it easy to create deeply collaborative and hyperlinked multi-user virtual workspaces, virtual exhibit spaces, and game-based learning and training environments that run on all major software operating systems. By using a peer-based messaging protocol to reduce reliance on server infrastructures for support of basic in world interactions across many participants, Open Cobalt makes it possible for people hyperlink their virtual worlds via 3D portals to form a large distributed network of interconnected collaboration spaces. It also makes it possible for schools and other organizations to freely set up their own networks of public and private 3D virtual workspaces that feature integrated web browsing, voice chat, text chat, and access to remote desktop applications and services.
