Cool name, isn't it?
This is just my collection of little things in the Java language that are probably unexpected or look funny - or spooky at first.
Also keep in mind that this is more a collection of failures and puzzles, so it might be the opposite of good code.
Obviously, this is targeted to kids or very junior programmers.
Hopefully it will grow over time, this is only the start and a place to put in the things I stumble over in my or others code and to not forget about them.
