Mechanical Horror is a writing genre which I have come up as a modern interpretation of Cosmic Horror. Instead of creatures and god-like beings outside of human comprehension which would drive you insane just thinking of their existence, the focus is on machines, technology beyond comprehension. Machines and contraptions so bizarre that they possess your soul and mind, seep into your very conciousness and being.
Mechanical Horror is interesting as it much more relevant to today's world and technology. Writing about the incomprehensibility of technology or machines gone askew makes one think deeper about the technology around them.
