| Amazing. My head is spinning just thinking about this! |

| wow
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. |

| 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! |

| 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. |

| 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!

| I have a sliding block puzzle black and white cranes(?) of design M. C. Escher "E 128" made by Pussycat in Bad Salzfluen Germany distributed by Cordon Art Baarn Holland. Does anyone know of this and movements technique of the tiles to arrange the puzzle? |
| Richard Fine | 2008-03-11 02:35:26 |
| I recently viewed the documentary "Achieving the Unachievable," which reminded me of the influence that M. C. Escher's work has had on my life. I have been creating abstract graphics for nearly 40 years, and would never have started had I not seen some of his works as a teenager.
Thank you!! |

| Neat stuff!
I am intrigued by the fact that artists were needed to do what mathematicians and computers found impossible - something mentioned in the Robinson article in SIAM News.
What we are looking at is beyond the bend in a Möbius strip - on the other side of the looking glass and perhaps even some transforming view caught in the bend itself.
If there is so much math in this drawing how much is there in a story by De Maupassant or a fugue by J. S. Bach !
The realm of creativity is nothing if not "curiouser and curiouser."
Keep looking in.

| Are we talking about the center of the whorl? |
| Tony Jones | 2008-03-07 22:35:13 |
| Is the hole in the center of the whorl an infinity? |
| why his painting have no color? |
| for Kaka poop | 2008-03-02 04:35:42 |
| The reason that his toilet is so far away he can't even run there in an hour! |
| Escher is so smart, I even need to do a research project on him what a good thing to have this website! |
| George Wu | 2008-03-02 04:31:10 |
| What a nice thing you guys have done, but it is still not perfect . |
| hatice | 2008-02-29 17:47:43 |
| As logical it is, these pages are great for the information. |

| very special person.good to know he was here. that´s real art |
| ron davis | 2008-02-23 09:29:14 |
| just discovered both escher and droste but find it similar to work done recently by banyi. Mostly sold as children books. I was wondering if there is a connection. |

| literary ''intrigueing'' . I saw this site about 2 years ago
when i worked as a librarian in a lawyersoffice. The term "DROSTE-effect" is also applicable in some cases, but
i could not find an example.
Some days ago i visited the exhibition '' the dream of Piranesi in the Teylers museum in Haarlem "
There you can see and experience Escher's great inspirator.
And ! a reason to get back to this site also!
BTW, I own some old DROSTE tin's , however i am storing tea in it... |

| inpressionant!!! he is a genious!!!! juste brillant!! and a incredible from Leiden University!!!! |

| Kakapoop | 2008-01-28 13:31:51 |
| what is the reason Escher never made it to the toilet on time |
| John Rood | 2008-01-02 23:00:53 |
| Very Cool!
Math, CG, the modern world!
Completion of an inspiration. |

| I just watched your Princeton lecture and it was great. I hope you guys have recieved a lot of money to start your next project. I have been making some short loop stop motion animations and ran into some funny math problems luckily my little brother works for a company doing AI research. Any way good luck with your projects in the future. |
| nicole | 2007-12-22 20:57:05 |
| ok guys is it me in the "droste effect",
"The resulting Droste picture is preserved under scaling by a factor 256=28. You can view this picture as a cycle of 8 frames, each time zooming in by a factor of 2." there is a white face in that picture (the patch of white next to the painting of the boat.) |

| My grand parents were Conrad and
My granparents were Conrad and Rose Droste. Could they be the same ? My Mother was born in America but my Grand parents came from Germany |

| I like this web sides. Im trying to find new principles of MCE works and I think this work perfectly. Thank you very much Im enjoy to see Im not alone at this world without fantasy.
b JOIN MCEworld!!!! /b |

| Looking for interesting facts |
| pretty cool i like what you did i enjoyed the videos it helped to show what he did inside of his works with the droste effect it was cool to see them straigtened out also |
| Wow! That's a really amazing peice of artwork. I'd been wondering about that white spot for quite some time. I'm glad there's some people out here who attempt stuff like this! |
| LASZLO AJKAI PAPP | 2007-11-27 20:27:06 |
| Thanks for your great work!
Wish M.C.E could see .. this exciting brilliant team work.

| Far away in the heavenly abode of the great god Indra, there is a wonderful net which has been hung by some cunning artificer in such a manner that it stretches out infintely in all directions. In accordance with the extravagant tastes of deities, the artificer has hung a single glittering jewel in each "eye" of the net, and since the net itself is infinite in dimension, the jewels are infinite in number. There hang the jewels, glittering like stars in the first magnitude, a wonderful sight to ... read more |

| Thank you for the great Escher screen-saver. |
| cory ench | 2007-11-03 18:43:06 |
| I have been studying Eschers art for years being an artist myself and this project of your brings so much more clarity to how Escher's print works. Amazing project and very well done! :) |

| I just viewed Jean Bergeron's film last evening. I had to visit your site to see the visual details of the solution - wonderful! |
| Jill Houghton | 2007-11-02 03:28:20 |
| Wow! and WoW! Fantastic Site: beautiful work beautifully presented. I particularly like your set up of the grid page!
Thanks for making it available to plebs like me. |
