Vibration theory of olfaction have a vibrational energy mode compatible with the difference in energies between two energy levels on the receptor, so electrons can travel through the molecule via inelastic electron tunneling, triggering the signal transduction pathway. The vibration theory is discussed in a popular but controversial book by Chandler Burr. The odor character is encoded in the ratio of activities of receptors tuned to different vibration frequencies, in the same way that color is encoded in the ratio of activities of cone cell receptors tuned to different frequencies of light. An important difference, though, is that the odorant has to be able
The Legend of Zelda: Ocarina of Time hardware and software or subscribed to official magazines and clubs. In February 2007, "Ocarina of Time" was released for the Wii Virtual Console service for 1000 Wii Points. This version is an emulation of the Nintendo 64 version; as controller vibration is unsupported, the "Stone of Agony" item, which employs vibrations via the Nintendo 64 Rumble Pak controller accessory, has no function. A five-minute demo of the game can be unlocked in "Super Smash Bros. Brawl" (2008). "Ocarina of Time" was rereleased on the Wii U Virtual Console worldwide on July 2, 2015, this time including the original controller vibration.
