The way I think of it: firstly

* A closure is an environment in which variables are evaluated and 
stored

Once you 'get' closures, then:

* A continuation is a closure plus an execution pointer

Some closure examples I read a while back were not helpful. One I think 
talked about going across a railway crossing, getting run over by a 
train, and then rewinding to before you went across.

Using a continuation, you can rewind to before you went across, but 
you'll still be dead :-)

Regards,

Brian.
