Machine language time code

The machine language time code, or simply the time code, is a code appearing in a tattoo on Fry's butt, that causes release of the Time Sphere from the Galactic Entity (BBS).

Form
The code appearing in the film is as follows. 001100 010010 011110 100001 101101 110011

Observations
As you can tell, it is mirrored over the first three columns over to the last three and inverted over the first three rows to the last three. If you remove the last three columns, you can see that the first three columns are actually just the numbers 1 to 6 in binary.

It is interesting to note that it has yet to be truly explained where the time code comes from or how it ended up on Fry's butt in the first place. The code was put on the frozen Fry's butt by Bender, using a flap of skin from Lars, but it only existed on Lars' butt because he is a paradox time copy of Fry. This is an example of the. However, in the original draft of the script, Bender, while waiting for Fry to come back from the future (this being Bender 2, who gets kicked into the freezer tube), watches the lottery and writes down the winning numbers, converts them to binary and mirrors them, then inscribes them on Fry's butt, hiding them from Bender 1 and planning to return and win the lottery (unaware that he is doomed as a time paradox duplicate).

Trivia

 * Other examples of the bootstrap paradox include your future self travelling back in time and giving you something, Lars Fillmore, and Fry becoming his own grandfather.
