Tridimensional display of the generalized Ulam spiral displaying 4096 numbers [Visualisation tridimensionnelle de la spirale d'Ulam généralisée montrant 4096 nombres entiers].

Starting from the center of the horizontal plane, the 4096 little squares are numbered (N=1, 2, 3,..., 4096) when following a square spiral. The height of each tower is proportional to the number of divisors of N. The number 1 and the prime numbers are visualized by means of white squares Other numbers are visualized by means of colored towers (from red to yellow according to the number of divisors)
