Microsoft Office Labs
This is cool, if you get a chance check it out...
From the site:
Welcome to Microsoft Office Labs!
This site is a proving ground for ideas that come from regular employees and interns who work anywhere in Microsoft. Most of the code prototypes are developed by the Office Labs team in partnership with the teams that make the products. After all, they produce most of the ideas. Some of the things you find here will be web-based, others are downloads. Some will be a combination, something we call "software + services."
The prototypes you see here are like "Concept Cars". They aren't products or features of Microsoft Office. Don't expect them to work perfectly, or be available here forever. Just as when a concept car is shown at an auto-show, one or two or none of the ideas shown might make it into a future vehicle. Everybody knows its unpredictable, so don't go off thinking this is some kind of preview for future versions of Office, ok? Anyway, we thought it would be interesting to present some ideas we are exploring.
It's fun to try new stuff, but we also have a reason for putting these ideas out here in public. We want to find out which of these ideas are valuable, how people use them, and generally what you all think. To measure how effective the various ideas are we collect a variety of data about how you use these prototypes. If the thought of us gathering this data bothers you, please don't use these tools.
The prototypes really work, but as we said, they’re not products. We may enhance these prototypes based on your feedback as we test the ideas further, but these are free and there’s no official support. As with all such things, proceed at your own risk.
Every couple of months or so another prototype may show up. Sometimes more than one. Sometimes it’ll be longer. We hope you become a regular visitor and participant in the discussions. Let us know what you think!
One of the projects you can try is the Search Commands for Office 2007. This enables you to type in the command you are looking for and then click the one you want, very cool.
