Send Morse Code Over Stockholm By Laser
bigmac writes "KTH, Royal Institute of technology is celebrating 175 year anniv by making a very spectacular laser show. A green laser sent from the bottom of an old reactor building 30 meters below ground. The beam is then reflected over the city from the schools clock tower.
And yes, you can send your own laser-morse messages through their homepage!" Here's an image to chew on.
I wonder if echelon will be monitoring these transmissions... because we all know this is what the terrorists of the future will be using..
Can google enterpret Morse code?

Yes.
... that was up on slashdot a while ago. It allowed you to send messages that scrolled by on a 18x8 screen made of lamps in office rooms and play Pong on your GSM (see http://www.blinkenlights.de/).
It's not even that original, considering the fact that (at least here in NL) a lot of clip stations are continuously scrolling by SMS messages from random people. Everyone his 5 seconds of fame. Hmm.
The laser would be a fun way to ask a geeky other half to marry though.

Remind me not peer out the window next time I fly into Stickholm.
Anyone notice on the site that the university is giving a doctorat (honoris causa) to Bill Gates?
Nice one, Stockholm!
Click on "Ljus Telegraph" to send your own message. Ditt meddelande = Your message. Avsändare = Message sender. That's it. Quite simple.
You can get an English translation here. Sorry, Babelfish doesn't have Swedish yet ;)
After learning morsecode in the Navy, four of my friends and I had a lesson in how to behave in front of women. Beer had caused an unusually deep load displacement, and we sat in a train compartment and morsed whatever dirty words or sentences we could come up with.
.... ..- -. -.. . -.
Five drunken sailors and a young attractive(at least she seamed so, at that time) girl, gave us five hours of fun morsetraining. At her stop I found it appropriate to excuse for our childish behaviour - She replied that she had enjoyed our show, and as an old girl scout she had brushed up her morse code.
Sending morsecode in trains have never been the same after that:)
during my daily surf, two month ago, i found this to make my own morse code. have fun! =)

I attend this school; why do I have to read this on slashdot? Noone here knew. But then again, students don't seem to be invited to the 175 year anniversary.
"Stockholm by night"
In a symbolic meeting between academia and the rest of the world, Stockholm's night sky will be adorned by a beam of light. A beam that has its origins in history, is part of our time and endeavours towards the future. A beam reflecting the advancements of technology and enterprise. A curious beam.
From a point 30 meters below the face of the earth, where once Sweden's first nuclear reactor was, a laser beam is produces and is reflected by the tower where pioneers once sent the first TV signals across Sweden. From here, the light is further projected over the city before reaching its goal: the City Hall.
Warning: Do not look directly at laser with remaining good eye.
Some joyriding alien passing by Sol is going to pick up "All your base are belong to us" sent by some trite geek and thus begins the first interstellar war.

Does any translator know swedish?
Yup, not a problem

now we need to go OSS in diesel cars
Thanks for the instruction. Now how may I send a huge bat to the sky with this? We got some problem here in Gothem...
Actually it doesn't have to have sufficient power to ionize the surrounding air. Lasers are (if they're powerful enough) able to cause dipole radiation, without ionizing any molecules.
the dipole oscillations are oriented with respect to the polarization of the light, so this light is most intense if you see it from an angle perpendicular to the polarization.
It's true that weak lasers has to reflect of particles, but I'm sure that this laser is powerful enough to cause dipole radiation... (maybe the reason why the didn't just move the laser from the basement it's placed in)

Check out all the other photos from the event here.
I used to spend my summers nearby an observatory in the South of France, and they were using a pretty damn visible laser to measure Earth-Moon distance (I think). At night, a similar beam than in the article photo could be visible (can't remember the colour of it though), and that was 20 years ago.
Pretty impressive thing to see when you're a kid in the middle of nowhere in the early 1980's.

-- It's always darker before it goes pitch black.
It does look real. A green laser (Argon or DPSS) is 3-4 times more visible to the human eye than a red laser(which is the color most people think of when the word laser comes up). Since it's a direct beam and not being scanned to make pictures or effects, it looks even brighter. On a hazy night, a laser with a few watts (30-40) of power could be seen for miles.
