Seeing is believing

I have been planning on writing a post now for a couple of weeks but ran into a bit of a block and since I am easily diverted I have been following my twitter account (embarrassingly small) and posting on an economics blog that I follow.  I very rarely post anything to do with economics in the proper sense just the occasional link to other's thoughts. I do post on a wide variety of things that I find interesting or informative. Ran across this link today. Just did the first couple of pages and I get the point that my visual sense is easily deceived. That is sort of the direction I want to take my next post but I do not feel ready. I am reading a fun book by Oliver Sachs, Seeing Voices.  I wanted to finish it first but need to get back to it.
