I haven't written a maths-themed journal for a while, so here's a geometry quiz 
You'll need a ruler, a pencil and a compass.
If you're as clever as Gnomon, then see if you can do this one in your head
* * *
Start by drawing a circle with a midpoint O.
1. Draw a diameter of the circle, label the ends C and M.
2. Construct a perpendicular to CM at O.
3. Mark a point S where this perpendicular bisector intersects the circle.
4. Draw the perpendicular bisector of the line segment SO, creating its midpoint L.
5. Draw a circle, center L, with radius LS.
6. Draw a line from M through L, intersecting the small circle at N and P.
7. With the compass on M, set its width to P.
8. Draw a broad arc, crossing the large circle at A and E.
9. With the compass on M, set its width to N.
10. Draw a broad arc, crossing the large circle at B and D.
What have you just constructed?

I rough sketched it... It looks familiar... But I could be mistaken.
If I'm correct, it's in profile.

I've sketched it too, and I don't recognise it. 
I look forward to the answer though.

Well, to be perfectly honest, I could be suffering from pareidolia exacerbated by my particular location of my labels. My 'L' is looking like the pupil of an eye.

I don't own a compass. 
I could visualise it about two-thirds of the way through...

I tried it in Paint, and it looked like an eyeball to me.
But then, I have really skewed vision...

Mine's the head of a cartoon character. I recognize it, but I can't place it.

Like Dmitri, I could visualise it up to a point. But right from the start I was thinking to myself "is this Homer Simpson?"
Which would explain the "Greek" bit..... geddit?

Sorry - meant to say that I'm in bed and can't be bothered to go and get pencil, paper and compass etc.
Good luck to those with equipment to hand. I feel as though I'm being disrespectful to Icy by not doing it properly.

2legs - Hey, babe, take a walk on the wild side... Posted Nov 20, 2012
Am I the only one who was disapointed to find out that "Greek Technique" Isn't an addition to err
*cough*
a new... sort of
Position, one might
*cough*
use...? 
I lost the plot, right after the bit about drawing a circle... how big was it meant to be?

Sometimes h2g2 makes me so happy... My life is not in vein 
... you know that phrase, about 'little things amusing little minds'....? that 'little mind', is mine ... most of the time

Well, I'm definitely as clever as Gnomon, so I've done it in my head, and have got a scene for a sex scandal.

Have it drawn, I cheated and used AutoCad, I can see the face with the large eye and round nose. It looks very familiar - but I can't quite put a name with it! it is either an old comic strip or computer game - it is not Mickey!
I will go for Maw from Snuffy Smith.
Now I have to see the answer

Hang on, when you say "With the compass on M, set its width to P.", which end is on M?
