You can read her divine revelation of Hell here: http://www.divinerevelations.info/mary_k_baxter_a_divine_revelation_of_hell.htm
Imagine a ride based on actual Hell like this book suposedly is. Whether you believe it or not, the images Baxter portrays are absolutely horrifying. Skeletons in multiple pits burning to death, revolving tunnels(yes, just like in Duel), coffins with demons marching around them who shove spears in through slits, the burning rivers of hell where skeletons are chained ankle to wrist, lost souls in cells who burst into flames. This book contains images that are so horrific that even the most crude, basic recreation into tableux is still going to be quite terrifying. It may seem over the top but isn't this Hell is what most dark rides are getting at anyway? Why not go the whole way?
Even if you don't believe in Mary and her book, you should read it because the pictures she paints are truely terrifying, even if its all made up, which personaly I dont think it is (but still I have nothing against you if you are atheist or gay, to me you are all my brothers in themepark culture.)
Can you imagine a dark ride like this? It would be incredible.
I know from the Sally Corp's website someone was trying to recreate Dante's Inferno but this trumps that for sure.
Here is a video of some paintings by a few Korean artists who were shown Hell: http://www.divinerevelations.info/documents/pictures_from_the_pit/index.htm
There are some parallels with Mary K's story but that is a different topic. Just look at these pictures and imagine the dark ride that could come from them.
