If you put on a pair of polarizing sunglasses, things look different, and you'll notice things that you might not notice otherwise. Some thinngs are just artifacts of teh polarization, other things are actual characteristics of what you're looking at that were always there but weren't as easy to see. http://en.wikipedia.org/wiki/Polarizing_filter_(photography)

It's not so much a question of being sharp or not - whether from lack of sleep or drugs, if you're tripping you may feel great but your actual performance on any objective measurement is probably going to be well below optimal. I mean, take a look at this art: http://flyeschool.com/content/repetition-rhythm-and-pattern Very little of this addresses reality, but that doesn't mean it's not interesting.
