Sender: robinpb Robin Lead: Dedicated to irrigating flowers all over the road, letter area: ANSI Title: Coffee wall illusion by zixia dntx Sending site: Sun and Moon Guanghua Monday, April 8, 2002 02:05:34, site mail The coffee wall illusion is named after a 19th-century café in the English city of Bristol that had tiles like this on its walls The tilt of the horizontal lines in the coffee wall illusion is caused by simple direction-sensitive cells in the visual cortex Each tilt component combines to result in an overall tilt in the perception of the horizontal line. Interactions between cells explain how a continuous straight line on the retina tilts in the direction of a diagonal bar Detailed information can be found at the following URL http: www.xinli.net qq illusion class cafe wall.html For whom are the flowers blooming all over the road? The glory lasts for six years and the spring breeze lasts for a long time. Join hands in the morning and evening, let the wine be filled with wine tonight The Internet is leisurely and unrestrained. You and I accompany each other. We meet and get to know each other. Once again, my heart remains the same, a song of true love in front of the screen Source: Sun and Moon Guanghua bbs.fudan.edu.cn [FROM: 10.83.2.50]
