This carpet's design is based on the mathematical series of Fibonacci, a 12th century mathematician who had come to calculating how a population of rabbits mated, and found out that it  formed a specific number sequence. 0, 1, 1, 2, 3, 5, 8, 13, 21, 34,... where the last two numbers in the sequence are added to each other to get the next. (i.e. 5+8=13 and 8+13=21)

The interesting part of it is, that by dividing every number in the sequence with the number which goes before it (1/1 = 1 .. 2/1 = 2 .. 3/2 = 1,5 .. 5/3 = 1,666 .. 8/5 = 1,6 etc....) you approach a certain proportion which becomes stable at the number 987, and up, and this number is 1,618034 which is called the golden number, and it is precisely the same proportion as with the golden cut. It should be mentioned that the number is an APPROXIMATE value in the same way as PI.

Pierre Bismuth imagined an in theory infinite carpet in which he only keeps the first two squares which are each 10 by 10 cm. Their colour cannot be changed wheras the rest can be decided by the customer.
