In Germany you can be punished with up to one year in prison for publishing a mugshot: http://www.gesetze-im-internet.de/kunsturhg/BJNR000070907.html http://dejure.org/gesetze/StGB/201a.html

In Germany, leaving your car unlocked can cost you a fine of up to 2000 EUR (see StVO 14.1; StVO 49.1.14, StVG 24. In addition, you will lose your insurance coverage.

Not for a full-time live coverage (as opposed to short live segments of my favourite team's game interrupted by commercials, segments of parallel games and top-40 hits).

Here's a list of GPL software that has been approved by my 4 kids. I arranged them in the order I would introduce them:

• TuxPaint has been al all-time favourite of my kids, and it may be the only "game" you want a 3 yo to play.
• TuxTyping and TuxMath may become interesting later.
• TuxRacer fun downhill racer program.
• Celestia and Stellarium are two beautiful planetarium programs, but they might require an adult to navigate the solar system and find the most amazing nebulae.
• GCompris is a framework for educational software containing some nice games.
• Hedgewars is another favourite of my kids, but you might want to wait a few years before you introduce it to your kid.

As I said before, all of these are GPL, and all of them are available for Linux and Windows platforms (and IIRC also MacOS).

'Loser pays' does not work like this in Germany.
If you sue $BIG_COMPANY for, say, 100000 EUR damages and lose the trial, the legal fees for the court will amount to EUR 2568, the fees for your lawyer will be EUR 4051.95, and while your opponent may choose to spend a gazillion on his lawyers, you only have to reimburse him for another EUR 4051.95.
Tools to calculate legal expenses in Germany are readily available; here's on of them (in German language):

Of course it can get more expensive for the loser if the court decides that the need to hear e.g. expert witnesses.

My main objective for Google+ was establishing a simple way of online communication with my teenage daughters (who for obvious reasons refuse to add their parents as "friends") when they are abroad.
So I got a Google+ account, persuaded my kids to get a googlemail account, sent them an invitation - and learned that Google+ did not accept them as members because they were underage.
It may take a while until I give Google+ another try.

The Andromeda Strain has already been mentioned; I would also count Contact, Mon Oncle d'Amerique, L'enfant sauvage, Gorillas in the Mist and - with a grain of salt - Evolution as great science movies.
