Not Lovecraft, but some readers may be interested to hear of the popular culture Arcade Expo. 750 pinball machines, free to play for 3,000 convention attendees. It’s been and gone for 2015, but looks set to be back next year.
I wonder if something like a good pay-to-play digital Lovecraft pinball table, or three, might raise some cash for a local cats’ charity at NecronomiCon 2015? Someone would have to design the tables though, by re-skinning old public-domain classics, as I know of no Lovecraft themed tables.
