If you count those spiralling to the right as you go outwards, there are 55 spirals. A little further towards the centre and you can count 34 spirals. How many spirals go the other way at these places? You will see that the pair of numbers (counting spirals in curing left and curving right) are neighbours in the Fibonacci series.
Illuminati’s Cards game
Illuminati is a standalone card game made by Steve Jackson Games (SJG), inspired by The Illuminatus! Trilogy by Robert Anton Wilson and Robert Shea. The game has ominous secret societies competing with each other to control the world through sinister means, including legal, illegal, and even mystical. It was designed as a “tongue-in-cheek rather than serious” take on conspiracy theories. It contains groups named similarly to real world organizations, such as the Society for Creative Anarchism. It can be played by two to eight players. Depending on the number of players, a game can take between one and six hours.
