Hi all,
i have written  a program to show and analyze mathematical constants (pi, e, phi, sqrt(2), ecc.).
Now i'm able to draw 100.000.000 of digits (25000x15000) pixels...
The following image is from pi 10 million octal digits:
- change color every million digits
- luminosity show number of passage on same point
i'll post more if you are interested.

Have a nice day.
