Umm, when i'm looking at the grid, if I keep still for a little while, I notice that some of the lines seperating the squares disappear. I dunno if that could just be "tadpoles" or actual blind spots?!?!
Oh I also notice on the right, that the squares are more squashed together than the left. Is that due to the right eye being closer to the right side? I'm starting to get worried :x

but it's only up to 2001 and I dont know if this can be trusted, as this is a laser safety gear manufactor.
However, interesting to poke around there...
interesting that diode laser incidents are at 1.1% at the bottom of the list.. LD users are the smartest..
