Allusions in the artwork. Particularly referring to the [http://www.discogs.com/artist/Incredible+String+Band,+The Incredible String Band], for whom [[Boards of Canada|BoC]] have a great deal of respect, and whom they apparently see from time to time. The lyrics section reveals that they have sampled the ISB occasionally; there's the old track "ithcus sound", a possible reference to the ISB track "ithkos". There's a general similarity in mood between Geogaddi and such ISB songs as "Waltz of the new moon" (HBD). It has also been observed that the title "Geogaddi" might in part refer to the ISB song "koeeaddi there" (HBD again).

The front covers of both albums. Note the very similar font used (Bauhaus). Faces obscured. (in [[Music_Has_the_Right_to_Children|Music Has the Right to Children]], it seems artificial whereas in [http://www.discogs.com/release/217169 isn't anything] it seems to be intentionally caused by overexposure).

[Khov] made a post on the watmm forum about one of the small artwork pictures on [[The Campfire Headphase]] cover which obviously has been taken from [[https://web.archive.org/web/20051125115339if_/http://www.iit.edu:80/alumni/updates/yearbook/1970s/images/campus%20and%20student%20in%20computer%20center%201979.jpg this 1979 yearbook picture]].

The formula 3n(n-1)+1. This gives the sequence 1, 7, 19, 37, 61, 91, .... These are the centered hexagonal numbers. The nth centered hexagonal number is 1 more than 6 times the (n-1)th triangular number. You can make a series of hexagons of different sizes using coins (or indeed small hexagons). The first degenerate case is a single coin = 1. You can place six more coins around this one to make a hexagon with 7 coins. You can place twelve more coins around the outside of this hexagon to make a larger hexagon with 19 coins. And so on, adding another eighteen to get 37, then another twenty-four to get 61. My own illustration of this is below.

A pyramid or triangle of 703 dots made up of 296 dots on top, and a further 407 dots below. The Hebrew words in the picture are the last two words of Genesis 1:1, namely, the word for "and", and the word for "the earth" (Hebrew is written from right to left). The gematria for the words for "and" and "the earth" are 407 and 296, respectively (400+1+6, and 90+200+1+5; for further details on gematria, you can do your own research). The total for these two words is 407 + 296 = 703. As it happens, 703 is a triangular number, meaning simply that 703 dots form a triangle, as shown in the image. Triangular numbers can be expressed in the form 1+2+3+...+n-1. 703 is the 38th triangular number, 1+2+...+37 = 703. The number 38 is the sum of the rows of the magic hexagon; this sum is known as a magic constant.

Triangular numbers have the general formula n(n-1)/2. E.g. the 37th triangular number is 37×36÷2 = 666. Combinatorially, the triangular numbers are the "choose-two" numbers because they count the number of ways to pick 2 objects from a set of N objects (not counting the order by which you pick them).

 

37 crops up a lot here. Note that 407, 296, and 703 are all divisible by 37. Also note that if, against convention, you were to count 1 as being the first triangular (instead of the zeroth), then 703 would be the 37th triangular number.
