Russian grammatical advice?

[Im_Beta_00]

I need advice on making a Russian Ouija Board for a cheap (i.e., inexpensive)
movie prop. I don't want to put the "OUIJA" trademark on it, as that would
turn it into an EXPENSIVE movie prop, or at the very least, involve a lengthy
permissions process, and that costs money, too. So at this point I would
rather have something a whole lot less expensive, like "RASPUTIN SPEAK" in
Cyrillic, (with a picture of Grigory Rasputin varnished onto a piece of 16"
pine board), but before I do that, I need to know if Russian has a vocative
case for its nouns like Classical Latin does.

What do I know about the Russian language? Well, not much, except that it has
more sounds than English has, and the Cyrillic alphabet is employed to
represent it, so if you don't answer in English (and English
transliterations), I won't be able to make heads or tails out of what you've
written.
