A couple of months ago I posted this[0]:

    The Point of the Banach-Tarski Theorem
        – not just a curiosity

That spawned a lot of discussion. Indeed, there are many many submissions[1], and some spawn considerable discussion, others are still-born.

The Banach-Tarski theorem is a lovely result, and I look forward to seeing what people say about this new presentation of it.
