Spectrum Games has a new RPG of Lovecraftian horror available, called Macabre Tales rulebook. Looks like you play it using dominoes!
To quote the game's description: "Macabre Tales is the dominoes-based RPG of Lovecraftian horror that strips out the "contributions" of later authors and focuses solely on what Lovecraft himself created. Spectrum Games, known for accurate emulation of various genres in their products, offers a brand new take on role-playing in the terrifying and abhorrent world of Howard Phillips Lovecraft. Will you emerge from the experience unscathed? Or will your mind snap in the wake of all the hidden abominations that lurk in the shadows, just out of sight of humankind?"
