just chanced upon this page featuring a Battery Operated Tongue Vibrator ... urgh... frankly speaking, i can't stand any form of body piercing - ears, nose, cheeks (yes, even during the Thaipusam festival), tongue, nipple, belly button, etc etc... as a matter of fact, i can't even stand injections! :p i remember the only time i closed my eyes when i was watching Alien 3 (with Sigourney Weaver) many years ago was when there was a scene of someone getting a regular injection.. haha.. i didn't even squirm when i saw the actual "alien" later on... durrhh?? :D

learnt about syn-es-the-sia n. Physiol. Sensation produced at a point other than or remote from the point of stimulation, as of a color from hearing a certain sound (fr. Gk, syn = together + aisthesis = to perceive). umm.... fascinating...

People who taste colors....see fragrances...smell sounds...Synesthesia is an involuntary joining in which the real information of one sense is accompanied by a perception in another sense. In addition to being involuntary, this additional perception is regarded by the synesthete as real, often outside the body, instead of imagined in the mind's eye. It also has some other interesting features that clearly separate it from artistic fancy or purple prose. Its reality and vividness are what make synesthesia so interesting in its violation of conventional perception. Synesthesia is also fascinating because logically it should not be a product of the human brain, where the evolutionary trend has been for increasing separation of function anatomically.
