A friend showed me one of those--fabulously quick to whip a few
servings' worth of cream at a time--and I liked it so much she
brought me one back from Australia. I have never seen one for sale
here quite like that, but I did find one I like better. It has the
same design of the whisk spiraling around perpendicular to the rod of
the whisk, but is stainless steel and has a ratcheting handle--you
push the handle up & down, and the whisk whirls around. I got it at
King Arthur Flour, but they no longer carry it.
Google eventually came up with a few sources for the same whisk
shape, but not the ratcheting handle too:
