'Big O Pro' - powerful programming software. Name comes from the mathematical Big O notation.

Logo detailes amplifies that connection:
- multicolored graphs inside 'O' are based on the most common Big-O function
(exponential-cubic-quadratic-log liner-liner).
- geometric type, straight lines and circles.
- proportional spacing and sizing
(big O = 3*x of the text height, letters spacing = 1/4*x, etc.)
