WHERE DOES IT BEGIN!?!??!?

you know what?

It's like a circle.

It can begin anywhere.

Where does any triangle start?

At the end.

The beginning starts at the end of some other beginning's end which began when another beginning ended. And obviously that beginning had began upon the first beginning's end.

From a box ^^

It depends how you are looking at it . Could start at the bottom right corner could start on the far left. I truthfully think it starts bottom right corner cause if you look very closely you'll start to see it go left the turn into a staircase type thing then go's back down and then starts over from the bottom right.
