|great job. A really interesting retrospective to Escher's work.

|I thought you might like to know about my play Impossible Steps inspired by Escher's Ascending & Descending. Further info is available at our website, I'd be happy to advise you its details. This play had a three week run at the Rosemary Branch Theatre, London 6 weeks ago. I am planning other UK productions as well as a tour of Holland where I hope to put on the play at Escher's Arnhem school which is said to be his inspiration for Ascending & Descending.|

|Prof. Stefenhagen's presentation in Cologne was 10 times better and more coherent and a hundred times more witty than the web-presentation here.
For centuries mathmatics lacked of comprehensibility (and often avoided to have) but since two or three decades some protagonists respect understandability.
One of them ist Stefenhagen.
Thank you, Peter.|
|Thanks for explaining the whole procedure so well that I was actually able to understand it!
Those animations made my head dizzy!

|Thank you for a very decent approach, to math art culture.|

|I have a reasonable collection of his work. I am delighted with this magnificent addendum.|

|i am inspired byEschers work|
|A great site, I've never thought about this efect as a mapping in the complex plain. It's great!! I wonder if this was the original intention of Escher?|
|um hi HOW DID HE DIE?!!!!!!!!!!!!!!!!!!!!!!!!!!|
|fantastic, hypnotic, perfect. i've always liked escher, but i didn't know how exactly smart and open minded he was.|

|this man has accomplished everything i could dream of becoming.he is the worlds greatest graphic artsit. i own all his books and have done a lot of research about himn and i am truly disapointed that i was born after he died unabling me to ever meet this astonishing man.|

|Fascinated. Prof. Rónyai draw my attention to your project, I to Escher.|
|carolyn kinnison||2008-09-02 20:19:01|
|this was unique and interesting
|have an interest in the loop as it related to thought processes ...|
|Gonzalo Gómez||2008-08-25 03:12:36|
|I have always admired Escher´s work. In books is impossible to see what you have discovered. Thank you.|
|Great work ! thanks for the videos, very enlightning !|
|this man does nice pictures.... please send some to my email|
|Smil Ochs||2008-08-12 22:05:42|
|Fascinated by the way our eye is conditined to interpred 3-D effects|
|Mooie, instructieve site! Tony Roodvoets|
|This is great. I spent the weekend scrutinising a graphic like the ones above trying to figure it out (I was actually tripping), and so with the info on this I can draw my conlusions. Thanks.|

|I have to old DROSTE trading cards. I would love to know the age? What there worth? and the history on them. I can send you pictures and would appreciate any help.
Thank you Debby|

and thanks a lot for the site. I discovered Wikipedia through it in 2003 (but not the guest book until now :D) and the site will always have a place in my heart!

Merci de laisser ce merveilleux travail à notre disposition.
Quelle qualité de présentation
à la hauteur du grand génie que fut Escher!|
Congratulations on your excellent project. I would like to know what would be the result if both variables were zero (i.e., a=0 and b=0). I noticed that this combination is absent from the galleries and I was wondering why.

|Radio-Canada, the French language branch of our national radio
and television agency aired the documentary "Achever l'inachevable"
last night. I must confess I had never heard of your work on this
topic before, but really this documentary is a small masterpiece for
promoting mathematics and relation to arts. Congratulations for your
work and for the quality of this exceptional document these people
made from your work. I was really happy to sit with my 9 year old
daughter telling her I knew personally all the mathematicians
(except for Douglas Hofstadter who I never met) in this movie.
She was fascinated with the whole story and solution of the "mystery".|

|I watched a documentary about how "filled in the blank". Excellent and fascinating.
Love your site.|

|Thank you for your excellent lecture at Magdalen College, Oxford, yesterday.|

|escher I\\\\\\\\\\\\\\\'ll like you to tell me alittle bet about you .
I know your name is escher.|
|omg nice site for my paper ah.|
|Matt Amy||2008-05-08 16:25:27|
|Amazing. My head is spinning just thinking about this!|
|Ernö Keszei||2008-05-04 14:48:39|
nice site.... and i'm now going to hear a conference in Pisa exactely about this subject|
|umberto sampieri||2008-04-29 21:12:54|
|interesting. reached the site via www.sns.it. I am a former mathematician graduated in Normale. At present in business but always fascinated by math and its application. please add my name to your mailing list|

|Heard the talk by Prof. Stevenhagen yesterday in Konstanz.
Wow! I had already been fascinated by the loop idea in maths
since Goedel-Escher-Bach. But I had never had the clue as to
how the picture-gallery picture worked. Thanks for the
mesmerizing explanation. ... and showing how to take log of
a picture. Suppose I shall be looking for Droste-effects each
time in the supermarket from now on.|

|Do you have higher resolution versions of these images? They are amazing.|
|Susanna Risa||2008-03-27 18:19:09|
|I heard Prof. Lenstra's lecture at Math Festival in Rome... what can I say?
You all made a truly fascinating work, perfectly balanced between math, art and disclosure... not to mention humour.
Thanks for sharing it on your site!|
|Ali Legenhausen||2008-03-20 08:17:49|
|Hello. Nice pictures. Very interesting. I have a book of Escher drawings. I wonder if something similar could be done with any of his other drawings. Have you drawn any other pictures based on similar mathematical principles?|
|Brian Davis||2008-03-19 16:50:05|
|Facinating! Absolutley Facinating! Will there ever be another Escher???|
|Gianni Campanile||2008-03-17 08:25:56|
|Dear prof. Lenstra, your lecture about Escher and Droste effect was exteremly interesting, clear and very amusing, even for my 11 years old son.
Thanks again, and I hope you\\\'ll be here in Rome next year.|
|Michele Ranieri||2008-03-16 22:53:09|
|Dear prof. Lenstra
Thank you very much for your lecture at Math's Festival today in Rome. Nice, clear and exciting! I won't find peace until I draw a "-3 snakes". I'm studying computer science and I wish I had teachers like you.|
|Antonio Ianiero||2008-03-16 18:48:19|
|Dear prof. Lenstra,
this morning I attended your utterly interesting lecture here in Rome at Math's Festival, and I would like to thank you for the clear explanation and the beautiful Mathematic you shared with us!
