I was recently on my way to one of my sculpture classes, and decided that I was going to get baked as hell.  I lit up a bowl, got a solid 3 rips, and then cashed it and then started walking to class.  In class, I finally noticed why so many artists were/are drug abusers.  Everything comes alive and makes sense in your mind.  I don't really know how everything worked, but my personal artwork to understand depth perception on 2D and vanishing points in paintings suddenly became so amazing that I almost shit my pants.  Seriously, has anyone else noticed an extreme change in perception of arts once they were blazed?
