I didn't know you worked for Microsoft? :-p

Only 1 meter thick?
From http://history.howstuffworks.com/middle-ages/castle2.htm
"The outer curtain wall was high, thick and made of stone or brick. Walls could range from 6 to 10 meters high and 1.5 to 8 meters thick."

So that worked well then...

I won't ask why you are sticking pigs up chimneys... :-p

It's here: http://slashdot.org/pollBooth.pl?qid=1785

I guess you don't get many visitors then?

Oh, and did you get any mail recently? :-p

...for some nice gates: http://news.bbc.co.uk/1/hi/uk_politics/8064794.stm and a moat: http://www.telegraph.co.uk/news/newstopics/mps-expenses/5315477/Clearing-a-moat-costs-thousands-of-pounds.html

Fascinating. It would be interesting to talk to a blind person and see if they experience anything like this...

Following Ley lines? :-p

The odd thing is, I don't need magnets to navigate back to a point I started at. I couldn't easily tell you which way is north, but I can usually point in the direction of my car/hotel/etc from anywhere in the city provided I walked there (without any deliberate attempt to memorise landmarks or turns).

I was once 'lost' in Munich - lost in the sense of being able to point in exactly the direction of my car, just not being able to find streets that would take me that way. I came back via a completely different route, apart from the last 200 metres or so, but still knew exactly which way I needed to be heading...

I used to get a slight headache and involuntarily shudder whenever we drove under high voltage power lines as a kid. It doesn't seem to happen now I'm grown up, but I still seem to have some sensitivity to magnetic fields - I worked for a company that sold "magnetic health products" and had to insist that I really didn't want any of their stuff near me because it would give me a headache... Of course, some of that could be psychological, I've not experimented to see if I could tell the difference.

Also, with older mobile (cell) phones I used to be able to tell when they were broadcasting (most likely polling the base station as it wasn't making/receiving a call) by a kind of slightly painful sensation in my hand if I was holding it. I only get that now with modern mobiles if my hands are wet.

The three of us together can bring the world to its knees! (With laughter)...

Like EDF, Groupement des Cartes Bancaires, or Telekomunikacja Polska and Slovak Telekom are then?

I can't see the appeal doing much except perhaps reducing the fine somewhat...
