A mind reading experiment
Did you know your computer can read your thoughts? Here are the first few sentences of the famous book the Wizard of OZ. Let's try an experiement in mind reading.
Dorothy lived in the midst of the great Kansas prairies, with Uncle Henry, who was a farmer, and Aunt Em, who was the farmer's wife.
Their house was small, for the lumber to build it had to be carried by wagon many miles.
There were four walls, a floor and a roof, which made one room; and this room contained a rusty-looking cooking stove, a cupboard for the dishes, a table, three or four chairs, and the beds.
Instructions
Pick any word in the first line of the Wizard of OZ. Count the number of letters in the word you have chosen, and call this number of letters x. Then move forward x words and count the number of letters in the next word you stop on. Do the same again, count the letters in the word (x), and move forward x more words. For example, if you chose "in", it has 2 letters, so count on 2 words to "midst". It has 5 letters, so count on 5 words to "prairies" and so on. Keep on doing this until you first enter the third sentence of the book, the sentence starting 'There were...' And note the word where your count stops. Think very, very hard about that word. Keep concentrating... Then read on.

Current Prize CompetitionsA Limerick from the cs4fn Competition
A computer was heard to complain,
That Scarecrow's completely insane...
He could cipher accounts,
Massing mega-amounts,
If only he had him a brain!
The Maze
In the next room furious games of noughts and crosses are being played
Through a wall letters are swirling all over the place.
A corridor also opens out into a courtyard
The door after that goes into a studio where a quiz show is going on.
