You can find the product and relevant information here. Essentially they are making custom FATE dice and the first set is themed to the Dresden Files. I'm not a particularly huge fan of customized dice myself for practical purposes - it can be very easy to confuse which symbol is which in the heat of the moment, sometimes on purpose - but I do have to agree that they can help with getting into character or staying with the theme of the game. After all, when you are rolling to see if your wizard succeeds at a task do you want to see a bunch of numbers (or + and - signs as the case may be) or arcane sigils? I know I rather enjoy using my Japanese dice when I play L5R (though I don't always use them for the above mentioned reason.)
So, if it meets your interest why not mosey on over and take a peek. Maybe you'll find something you like.
