Stimulated by the work of the first prize "The Leaning Tower Illusion", I tried to produce a similar illusion design, with failure as shown below. No larger tilt in the left girl! I misundersood that the illusion is one of the classic angle expansion illusions.
Illusion work with weak illusion

Then, I imagined a simple image may be better. But the result was negative,
as shown below. No larger tilt in the left trapezoid. Therefore, the Leaning
Tower illusion is NOT one of the classic angle expansion illusions.
Little or no illusion
It seems that the Leaning Tower illusion need curved line segments, as
shown below. The left object appears to tilt more than the right.
Good.

I had missed an excellent site of visual illusions. Thus I have made a link from my link page to the site shown below. <March 7, 2007>

Ichiro Fujita, professor of the Osaka University, examined the relationship between the visibility of "Rotating snakes" illusion and age. As a result, the older the observers are, the more frequent those who did not see the illusion.. <February 8, 2007>
Previous surveys
Survey at the Osaka City Air Terminal (October 21,2006) "There was a negative correlation"
Survey at the University of Air (December 25, 2005) "There was no correlation"
Survey at the University of Tsukuba (July 7, 2005) "There was no correlation"
Survey at the VSS2005 Demo Night (May 9, 2005) "There was a negative correlation"
In the library of the Tohoku University, Sendai, Japan, Kitaoka's illusion designs are exhibited with geometrical illusions in the days of Wundt. <February 7, 2005>

**** SECOND CALL FOR ILLUSION SUBMISSIONS: THE THIRD ANNUAL BEST VISUAL
ILLUSION OF THE YEAR CONTEST****
http://illusioncontest.neuralcorrelate.com
*** We are happy to announce the world's 3rd annual Best Visual Illusion
of the Year Contest!!*** The deadline for illusion submissions is February
15th, 2007!
The 2007 Contest Gala will be held in Sarasota, Florida (Van Wezel Performing
Arts Hall) on Saturday, May 12th, 2007 (7.30pm-10.00pm), during the week
of the Vision Sciences Society (VSS) conference. Refreshments will be served.
The 2006 annual contest, also held in Sarasota, Florida, was a huge success,
which drew numerous accolades from attendees as well as international media
coverage. The First, Second and Third Prize winners were Max Dursteler
(Universitätsspital Zürich, Switzerland), Peter Tse (Dartmouth College,
USA), and Gideon Caplovitz & Peter Tse (Dartmouth College, USA). To
see the illusions, photo galleries and other highlights from the 2006 contest,
go to: http://illusioncontest.neuralcorrelate.com
Visual Illusion Contestants are invited to submit novel visual or multimodal
illusions (unpublished, or published no earlier than 2006) in standard
image, movie or html formats. An international panel of impartial judges (including Akiyoshi Kitaoka) will rate the submissions and narrow them
to the top ten. Then, at the Contest Gala in Sarasota, the top ten illusionists
will present their contributions and the attendees of the event (that means
you!) will vote to pick the TOP THREE WINNERS!
The renowned sculptor and artist, Guido Moretti, has created three all
new amazing works of art to serve as trophies for the TOP THREE winners!
See the trophies at: here
Illusions submitted to previous editions of the contest can be re-submitted
to the 2007 contest, as long as they meet the above requirements and were
not among the top three winners in previous years.
Submissions will be held in strict confidence by the panel of judges and
the authors/creators will retain full copyright. No illusions will be posted
on the illusion contest's website without the creators' explicit permission.
As with submitting your work to any scientific conference, participating
in the Best Illusion of the Year Contest does not preclude you from also
submitting your work for publication elsewhere.
Submissions can be made to Dr. Susana Martinez-Conde (Illusion Contest
Coordinator, Neural Correlate Society) via email (smart@neuralcorrelate.com) until February 15, 2007. Illusion submissions should come with a (no
more than) one-page description of the illusion and its theoretical underpinnings
(if known). Illusions will be rated according to:
. Significance to our understanding of the visual system . Simplicity of
the description . Sheer beauty . Counterintuitive quality . Spectacularity
Visit the illusion contest website for further information and to see last
year's illusions: http://illusioncontest.neuralcorrelate.com
Submit your ideas now and take home this prestigious award!
