I would have loved to contributed to this thread myself, but alas, I do not have much time in my hand right now. I haven't even read the last few posts to this thread. Maybe, some other time. Zen, beautiful illustration of perceptual illusion though. I guess I will have to go with it for now. Keep posting these enriching philosophical musings. Rest assured, I will read them all when I do have time. Great discussion guys, keep it up.
