I'm surprised how many people thought this was a bad idea. I teach computer science and I have an air mouse from gyration. It takes a little getting used to, but it makes it possible for me to use the mouse on my computer from across the room. It is useful for anyone who needs to use programs other than powerpoint(like an ide) while giving a presentation.
There's a well established practice of sending mail to yourself so you can show the postmark on the unopened envelope and show the court that the USPS attests to the date on it. That is completely useless. Here's why: take an envelope and address it to yourself. Put a stamp on it, and tuck the flap inside the envelope, but do not seal it closed. Mail it. When you get it back, put something in there (like last night's lottery numbers or the score of a football game.) Seal the envelope.
Congratulations, you have an envelope that is postmarked September 8, that contains the lottery numbers for September 10th!
"I might get modded off-topic for saying this, but..." on slashdot people regularly post the question "How would slashdot react if Microsoft did this?" This post is usually modded insightful because the mods see it as thinking outside the box—it looks like you are breaking away from the herd mentality when you post this question. The only problem is that people regularly post this question, or a paraphrase of this question, so it really isn't too insightful.
This post usually gets one of two responses: "It would not be the same because..." or "Slashdot is not one person, the members of the slashdot community can disagree with each other."
Thermodynamics makes this almost impossible. The second law says that it is hard to do useful work with energy that is spread out like the heat on an asphalt road. If you try to get energy from heat, you can not do any better than Carnot efficiency. A machine that transfers heat from a 100F road to 60F air will be less than 7% efficient.

"and the taxes" ... They are selling these in bulk to national governments. I doubt that any government is worried about paying sales taxes to itself.
I've seen this comment somewhere before. Although this comment is interesting, it is off-topic and redundant.

Think of the children...
It looks like google just created a clone of the ESP Game.
