As I've noted before, I dig Vladimir Nabokov not just for his subject matter, but his lush, image-centric writing style. Both Nabokov and his wife Vera suffered from Synaethesia, a disease that makes the person associate different sensory responses with various stimuli; for example, in Nabokov's case, letters and words on a page caused him to see colors and other images.
The drug LSD reproduces these effects, but can be unpredictable, and people unused to dealing with the sensory perceptions might experience negative side effects.
Also of note is the video game REZ, which according to its sell sheet
- ...when sound and visual effects ultimately come together, Rez will open your senses to a totally unbelievable experience like nothing you have ever felt before.
Now, it is my understanding that you need either a Japanese PS2 to take advantage of this - that, or a modded US version.
