Do you miss playing Funhouse Dungeons? A manorhouse that seems to be slowly going as mad as its former owner? Maybe it is being manipulated by his ghost. Maybe it's the lair of a Malkavian. Maybe it was just designed that way from the start. Maybe its secretly a conduit for an elder evils, like certain large towers in New York City that may envolve Keymasters and crossing stresms... How about a dungeon which physically changes as your players move through it. Each time they trigger something in the dungeon, the map changes, keeping them disoriented and confused. What about the lair of some small underground nuisance. Kobold lair, Nosferatu lairs... Or what about the madness caused when people cram themselves in underground without planning restrictions. A warren of people carved into the ground below the city. Thieves. Refugees. Rats. Vampires. Anything could be down there in the madness of these rooms. Or maybe you want to put them in a room with one exit, many doors, and it seems like the doors don't lead to the same room each time... You can find them all in  A Box of Tricks 1 (if I get interest in more of these mad monstrosities, I'll likely release more)
