Ever see an Imax 3D movie? They use IR transmitters--about 10 banks of 50 LEDs each--to flood the large theatre. The signal sends data to the glasses which tell the LCD shutters which side should be on/off.
In a smaller room, a single bank of 10 IR LEDs should do it. I control lots of things around the office with IR. If your ceiling reflects IR well, just have a bank of 10 LEDs pointing up and you can fill a big room.
You can transmit regular serial data (with some error checking code) and use an IR reciever module (look for Vishay and Sharp as suppliers) that outputs TTL levels which your serial port may be able to handle directly or with a small interface.
IR "bits" at slower rates are generally transmitted as pulses of a 35-45 kHz tone. While many standards are self-clocking for reliability, you can send regular serial data, the presense of the tone for "mark" and the absense for "space"
While X-Ray is pushing it a bit, do any animals have IR vision? After all most photosensitive chemcicals and substances I know of (film, CCDs, etc) have no trouble with IR (and film does quite well with X-Rays).

Ya know, you'd think that, regardless of the metal fog that everyone's in when it comes to legislating the internet, it would be illegal to assume someone's else's identity.
Using a your domain as a return address for spam strikes me as terribly unfair. It's a shame there are no existing laws to put folks who do that in jail.
I used to own "boy.com" many years ago and gave up the domain for similar reasons. There would be a ton of email forged with that as the return address. The last straw was possibly illegal porno being posted to USENET with "boy.com" as the hosting site (forged, of course.) Back then--in 1995-1996--I decided to get rid of it because I thought it may be impossible to convince authorities that we had nothing to do with those postings.

You need to make sure that these fake addresses couldn't possibly disturb real people.
I own a domain that's one-letter off from the #1 site on the web. I find that people make this one letter change to avoid getting spam, and the email goes to me! I get thousands of emails a day to this account from people who do this.
I'd be careful that the fake email addresses don't annoy real people. Use fake TLDs.
I have some email addresses on my web site that are there solely for EmailSiphon to find.
Any message that goes to these addresses gets its sender blocked automatically by my procmail scripts.
Also, I scan the inboxes to find messages in real accounts that are substantially the same as the spamcatcher messages. Those, too, are deleted.
(I've also posted the spamcatcher address on Usenet.) The downside to this is that it takes a while to detect this. If I pick up my mail too soon, a spam may get through because the compare script hasn't run yet.
Not that it matters for this case, but has anyone actually been able to make money because they can track users bettter?
I worked for a dot-com (briefly), and though we tracked everyone's viewing and clicking history, we were at a loss to do anything useful with the info.

I doubt that this info is actually useful.
BTW: If you use Windows, Norton's "Internet Security" does a great job of blocking cookies and banner ads! It's transparent, so once you install it, you hardly know its there. Each time you visit a site that tries to cookie you, you can choose "Always allow for this site" or "Always Deny" (and also block ref-by!).
I agree! If the doamain is legal to sell, then perhaps they're violating their agreement as a domain agent.
Of course, try getting our current crop of "let's clean up Hollywood" politicians excited about allowing FUCK in domain names.
A little story: For about a year, I dropped out of my long career as a researcher and worked for a dot-com. They would meet for days on end about what dirty words should be filtered in chat rooms! They'd rather talk about that than actually making the products better. I finally left in disgust, and the CTO of the company who was a main force behind keeping chat clean was arrested for soliciting sex with what he thought was a 13-year-old girl on the Internet.

You plead guilty because you are guilty. It is an admission of guilt. The judge reminds you of what you're agreeing to when you enter a guilty plea.
That means is is guilty. He said it himself.
Here's one fact: AOL (Netscape's parent company) uses IE as the standard browser for its on-line service. If Netscape's manufacturer can't depend on it, why should we?

W3 Releases Amaya 4.0

· Score: 2
It was at a W3C meeting several years ago. I was working on a GUI HTML editor for a leading software company, and they came up to me and said:
"You should make sure your output looks OK only in Amaya. By making it look right in Netscape and IE you're part of the problem"
I replied that if we made the output render correctly in Amaya and didn't care about any other browsers, nobody would buy our product because nobody uses Amaya!
He started SWINGING at me! After this, I never paied any attention to the W3C ever again.
I used to work for a major "dotcom" (remember those?).
We were advised by our attorney not to save anything, and that policy worked. After 48 hours, logs were purged, after summary information was collected.
We'd occasionaly get inquiries from the FBI tracking down a case of Internet stalking or child pornography, etc, and we'd just tell them that our our logs get deleted after 48 hours. We'd follow this up with the page copied from our procedure manual.
This satisfied them, and they didn't ask us to change this policy.
There's no good reason to save internet logs for years. It can only hurt you, and never help you. THROW THEM AWAY, folks!

I find this hard to beleive, given that Imax claims the system is *sequential* left/right (alternating left/right frames).
Are you sure?
