An option for suicide "with elegance and euphoria" is how Lithuanian-born Ph.D. candidate Julijonas Urbonas described his Euthanasia Roller Coaster, currently on the drawing board. Urbonas' model of "gravitational aesthetics" would be a third-mile-long, 1,600-foot-high thrill ride engineered to supply 10 Gs of centrifugal force (a spin at about 220 mph) to induce cerebral hypoxia, forcing blood away from the head and denying oxygen to the brain. Euphoria (and disorientation and anxiety, but not pain) are likely states to precede the brain's shutdown.
