The Euthanasia Coaster is a concept for a steel roller coaster designed to kill its passengers. In 2010, it was designed and made into a scale model by Julijonas Urbonas, a PhD candidate at the Royal College of Art in London. Urbonas, who has worked at an amusement park, stated that the goal of his concept roller coaster is to take lives “with elegance and euphoria.” It is a ride to the death. The seven loops or “inversions” put the human body under such stress that it causes the brain to be starved of oxygen, as the heart simply cannot push blood against the enormous g-forces. Even if it kills you, it is designed to still be a fun death. An honourable thought, if rather macabre.

hmm. sort of a nice sentiment, sort of really creepy, imo.
