Escher, the Droste Effect, and Video Feedback

A few weeks ago, I mentioned I was reading Am I A Strange Loop? by Hofstadter. I was contemplating on writing about Video Feedback loops and my own childhood experience with two mirrors facing each other when I came across this fascinating website that I cant help but share it.
These are attempts to answer some questions about Escher's picture, such as: "what's in the blurry white hole in the middle? Using a bit of math, and some computer algorithm, Escher's methods are unraveled in fascinating detail. Its a feast for those inclined in Arts and Mathematics.

Am I A Strange Loop?

I ran to my local library to borrow "I Am A Strange Loop" by one of my favorite thinkers, Douglas Hofstadter. Its been a while since I read his last book "Godel, Escher, Bach" many years ago, and this new book will be a great feast. I've gone through the first hundred pages and this looks to be a very relevant book to be featured on archetyper.com by way of Hofstadter's constant reference to metaphors, analogies, symbols and patterns, revolving around the central idea that consciousness is a self-referential system, a Strange Loop.
