Read Sophie Maxwell's interesting article "Blurring Boundaries" about synesthesia in art and creative marketing where scent can be seen, flavours and liquors are inhaled for their delicious or intoxicating effect, and there's even a scratch 'n sniff cinema...

Which makes me wonder: Are we so underwhelmed by our sensory world now that we need to reach new levels of excitement or explore new "senses" to truly enjoy anything?
