Well, an easy Great Old One idea that doesn't involve you dressing up like Cthulhu himself would be to go as a cthulhu cultist. I don't no, maybe it's not an easy or great idea. The other day, I thought it would be a good idea to play with one of the rats while smoking, and the little bastard came up and lipped my cigarette. I kid you not. Anyway, here's some pictures and ideas. Hope it helps. Ph'nglui mglw'nafh Cthulhu R'leyh wgah'nagl f'htagn!

Of course, anything ratty enough will do; here's an actual scene from the movie Dagon

Just remember to be fishy and scaly about it, but here's a sketch of a fishman from dagon

Of course, it helps to avoid "what are you supposed to be" with enough creepy stuff, so here's some creepy Lovecraft cthulhu-ish stuff
Dagon's Chaos star

Elder God sign

And, the alternate Great Old One sign

Here's Cthulhu's own Yellow Sign

Finally, the good ol' chaos sign

Anyway, as far as easy ideas for an actual cthulhu mask... if you're not against wearing pantyhose on your head, you could destroy several pairs, attach like half the legs to the front octupus-style, cut yourself mouth, nose, and eye-holes, paint the thing green, and drop something small, heavy, and soft (like a hackey sack, koosh ball, something that weighs a little bit but won't hurt if it thwaps you). It would probably help if they were dark in color, and if you used a thick, green latex paint. And, of course, don't wear it until it dries. If you don't cut eye holes, you could paint that area thinner, so you can see through it; it would look more authentic anyway.
Anyway, hope any of this was useful in any way
