	<title>Finding an old book about teenage love and axe heads</title>
	<link>http://ask.metafilter.com/138688/Finding%2Dan%2Dold%2Dbook%2Dabout%2Dteenage%2Dlove%2Dand%2Daxe%2Dheads</link>	
	<description>[Bookfinder filter] Trying to find a book I read at school, in the UK, in about 1987. It was a book for teenagers, with two interweaving stories across different times: one thread involved a teenage couple in modern times, and the other thread was about some Norse warriors, including a berserker, in ancient England. The two threads were tied together by an ancient axe head. The final section of the book was written in a cipher. Bits I can remember: The berserker character hiding somewhere and holding the axe during some crisis, the teenagers in modern times finding the axe-head somewhere. The two teenagers meeting in a cathedral, and using a code to write to each other.&lt;br&gt;
&lt;br&gt;
The reason I want to find the book: The last 10 or so pages were hand-written in a weird code based on rectangles and dots. It was the code that the teenage couple had used to write to each other, and I think the last 10 pages were a coded letter from one of them to the other. At the time when I first read the book, I could not crack the code, so I never found out how the book ended.&lt;br&gt;
&lt;br&gt;
Years and years later, I realised that the characters must have been using the &lt;a href=&quot;http://en.wikipedia.org/wiki/Pigpen_cipher&quot;&gt;Pigpen cypher&lt;/a&gt; - the book was quite sneaky in that it described how the code looked, but didn&apos;t give you enough info to actually translate it without outside help.&lt;br&gt;
&lt;br&gt;
From what I remember, it was a pretty good book, and I&apos;d love to track it down now and work out the ending. &lt;br&gt;
&lt;br&gt;
This is all a bit of a longshot, but you never know with the power of the interwebs these days. Thanks!</description>

	<description>MANF ANGWA RDASM ORT. What does it mean? Mike Doughty&apos;s guitar has letters (like the stickers you&apos;d put on your mailbox) that spell out the above words, one per line. It&apos;s not rot13 or any other Caesar shift. Google turns up nothing. Nothing obvious looking at anagrams. Any ideas?</description>

	<description>Tell me what cipher I need for my daily commute. I want to write privately in my little notebook, without worrying what words might catch someone&apos;s eye.  Yes, I know nobody actually bothers looking at what anyone else is doing on the subway, but there&apos;s hardly even room in the car to move an elbow, and it makes me more self-conscious than usual.  Besides, I have an Issue about keeping my drafts hidden and secret.  I want to feel comfortable carrying around a notebook with my rough drafts and other sensitive material in my purse, while I travel around to the office and various office-related duties.  &lt;br&gt;
&lt;br&gt;
It doesn&apos;t need any actual security.  It just needs to be opaque enough for the casual gaze or snoop, and by its codeness, say &quot;this is none of your business.&quot;  I tried rot13 for this purpose, but I felt like I was tapping things out in Morse code.  The writing I did in rot13 was strained and telegraphic.&lt;br&gt;
&lt;br&gt;
Can you suggest a cipher that lends itself to being written quickly and fluently?  Or do I just have to practice a simple shift like rot13 until I get the facility to do that?</description>

	<description>Cryptofilter: My daughter is at summer camp and I can snail mail her or I can send email that will be printed out and delivered.  The email is fast but readable by whoever prints/delivers the paper etc.  Looking for a cipher that would be easy to learn and use... I would send her the instructions and keyphrase in regular mail then encrypt messages in the email.  I want it to be more than a simple substitution but simpler than a one time pad.  For fun and learning... any thoughts?</description>

	<title>Does anyone know of any famous codes or ciphers that have gone unsolved for lengthy periods of time or remain unsolved?</title>
	<link>http://ask.metafilter.com/7060/Does%2Danyone%2Dknow%2Dof%2Dany%2Dfamous%2Dcodes%2Dor%2Dciphers%2Dthat%2Dhave%2Dgone%2Dunsolved%2Dfor%2Dlengthy%2Dperiods%2Dof%2Dtime%2Dor%2Dremain%2Dunsolved</link>	
	<description>Does anyone know of any famous codes or ciphers that have gone unsolved for lengthy periods of time or remain unsolved?  I am thinking specifically of things like &lt;a href=&quot;http://www.maydaymystery.org/mayday/&quot;&gt;The May Day Mystery&lt;/a&gt; and &lt;a href=&quot;http://www.crystalinks.com/voynich.html&quot;&gt;the Voynich Manuscript&lt;/a&gt; (&lt;a href=&quot;http://www.voynichinfo.com/&quot;&gt;also here&lt;/a&gt;).  So things more like those and generally less like &lt;a href=&quot;http://www.unmuseum.org/beal.htm&quot;&gt;the Beale Cipher&lt;/a&gt;.   Maybe something to do with Art Brut or Outsider art or perhaps Kabbalic systems like Gematria.  Or, if all else fails maybe something by the Rosicrucians or Freemasons?  &lt;br&gt;
&lt;br&gt;
Put another way, I am looking for cryptic and complex visual systems that maintain an internal logic (however faulty or suspect) and ESPECIALLY anything having to do with the interpretation and/or decipherment of such systems.</description>

	<title>How does this riddle from &quot;Speak Memory&quot; work?</title>
	<link>http://ask.metafilter.com/6265/How%2Ddoes%2Dthis%2Driddle%2Dfrom%2DSpeak%2DMemory%2Dwork</link>	
	<description>In Nabokov&apos;s autobiography, &quot;Speak Memory,&quot; there is a puzzle of sorts.  It goes like this (from pg. 70): &quot;We subjected [Uncle Ruka] to a test one day, and in a twinkle he turned the sequence &apos;5.13 24.11 13.16 9.13.5 5.13 24.11&apos; into the opening words of a famous monologue in Shakespeare.&quot;  I&apos;m stuck, can anyone help?</description>
