User:Ruotailfoglio/Sarcone elliptical illusionSarcone elliptical illusion – Well, I am new here, I just try to publish an article on a new interesting optical illusion that may be of interest to the wiki community. If you don't like it, it's OK. Ruotailfoglio (talk) 16:01, 3 August 2011 (UTC)[reply]

  • Do you have any sources that talk about the illusion itself? The two sources in the article currently merely present the illusion without much comment. Powers T 22:17, 3 August 2011 (UTC)[reply]

There are a lot of popular visual illusion websites that include this illusion, some allow access only to registered professionals, like viperlib.york.ac.uk. I did a research in my huge optical illusion library, the illusion is cited and/or commented in the following books: Page 105, Amazing Visual Illusions, Arcturus Publishing, UK, 2011, ISBN 1848378300 Page 64, Eye Tricks, Carlton Books, UK, 2007, ISBN 1844427773 Page 172 (Deceptive ellipses), Big Book of Optical Illusions, Barron's Educational Series, USA, 2006, ISBN 0764135201 Page 38 (Which line is longer), Dazzling Optical Illusions, Sterling Publishing Co. Inc., USA, 2002, ISBN 0806983930 And in the mathematical review Alice&Bob (issue no. 25) I don’t know if this is sufficient... And if yes, should I use ALL these references?
