Tramolines, in caves, strung across ye bottomless pits of Llechwedd caverns in the mountains of central Wales (UK). So cool. Just pipe in the sounds of “monotonous whine of blasphemous flutes from inconceivable, unlighted chambers beyond time…” via some bouncy sonic shoggoths, projection-map monstrous faces on the rock outcrops, dim the lights a little, and you’re all set for some real-life whirling Lovecraftian madness 🙂
With this kind of tech and kit on offer, can a Kickstarter for some kind of Cthulhu’s Cosmitronic Circus be far away?
