Very cool ideas.
I think that the gaming approach to learning is a really good way to increase
fluidity in the way that tools are used and fluidity is the foundation of
mastery (and its fun)
I had an idea to create a battleship style of game where a random selection of
1's would be placed in 10 10 $ 0 and the task was to select only the ones by
finding the left argument to { . You could do similar challenges with {:: or }
It would be great to have a 'Games and Puzzles' section in the J wiki. I was
going to say in the beginner's section, but I actually think that it would
appeal to everyone.
By the way
