I really liked the XOR Linked List hack by Don Schwarz.
The sun.misc.Unsafe class is really scary, but it is interesting to know that it is there (at least on Sun JVMs).
Apart from anything else, it makes you feel happy that you don't have to do any pointer crap anymore.
Don't first public showing of the class was in Avoiding Checked Exceptions.
He has got a lovely twisted sense of humour! :)
