Thats the spirit .... research! But now the sun is up and I have to go water the garden , heatwave expected. keep us posted on results.
OK, here's what I came up with; it's a bit rough but gets the idea across.
I set out to see if I could match the rather irregular figures in the backround of the 10 of Swords (and also behind the throne in the Queen of Swords) to the magic square of Saturn to go along with Snuffin's observations about the sword hilts in the 10 of Swords.
The first thing I noticed was that most of the figures are sort of "squashed" 8-pointed stars, or maybe Maltese crosses. (I toyed with the idea they might be transformed versions of Crowley's Unicursal Hexigram, but that only has six points.) Using the two larger figures at the top of the 10 of Swords as a guide, I "normalized" the figures into regular polygons.
Next I noticed that the figures contain somewhat distorted images of interlocking "arrowheads" or stylized capital Greek deltas (think of the delta used as the logo for Delta Airlines). I decided to use contrasting colors and lines to bring these into sharp focus.
I then "pinned" this figure to the square of Saturn in a way that seemed to make sense (no rotation required). The results are attached.
I disn't realize until I was done that the central, green 4-pointed star loosely resembles the background figures in the 2 of Swords and, much more closely, the 7 of Swords, as well as (again loosely) the wings on the Knight of Swords and the Princess of Swords. It also mimics the hilts on the Netzach and Hod swords in the 10 of Swords. Interesting coincidence.
ETA: Here's the preliminary drawing for it. It's also interesting to note that 2 of Swords is Moon in Libra, the sign in which Saturn is exalted, and 7 of Swords is Moon in Aquarius, the sign of Saturn's traditional rulership. Seems to be a lot going on behind the scenes here.
