Bitcoin Magazine has been making a point to get back to their roots and have been offering some good content as of late , here ‘s a good piece on the history of the Bitcoin logo :

” Every aspect of the Bitcoin logo has mathematical rationale behind it; every corner was architected as much for practicality and form as it was for symbology and aesthetics.

These rationale are painstakingly documented (as well as the specific instructions on how to make a perfect BTC logo from scratch) in this Medium post. The author, Phil Wilson, had helped design both the second logo that Satoshi introduced in February 2010 and the orange one that we know today.

And the one we know today is riddled with symbols.

For example, the number eight pops up multiple times in the dimensions and geometry of Bitcoin’s design (e.g., the B is rotated clockwise 13.88 degrees — more on this later). Per the internet language 1337, an eight resembles a B, which is short for “Block,” according to Wilson. Many of the patterns that went into creating the Bitcoin logo’s design, like the circles that eventually made up the B, contain the number eight. The dimensions of other shapes (like the rectangles in the design) had a length of 12.5 (or, one-eighth of 100, thus representing eight yet again). ”
