An idea for the first glyph. There is a code called pigpen where the alphabet is split up with three letters into each section of a noughts and crosses board. The square bracket means look at the middle right section on the board. The 1 in the bracket means pick the first letter of the three which is P. See picy.
P is the 16th letter. If you count around the glyph 16 times starting from the top you get to 41.
The sum of the surrounding numbers is 328. The prime factors (prime numbers needed to make up the number) of 328 are 2, 2, 2 & 41! 41 is one of the numbers on this glyph.
For the second glyph. If you times 32 (the centre number) by 7/10 (from the status bar underneath) you get 22.4. If you go round from the common geometical starting position clockwise you get to 11.
Then using the prime factors thing again. The sum of the numbersis 275. The prime factors of 275 are 5, 5 and 11!
Are these coincidences? Unfortunately I think so. For the same method to work on two of the glyphs but none of the others probably means they are just flukes.
Instead of squinting at the numbers around the edge and thinking "wait a minute, is that a two or a three" I made a larger version. The numbers around the edge are now perfectly clear.
Get it here.
