Turns out Elon Musk's SpaceX logo has a hidden message

Logo design can be a complicated business. Even the most apparently simple symbols can go through multiple transformations during the design process, and a dodgy line here or off-angle there will have kept a graphic designer up at night. And it seems not even Elon Musk is immune to the agony of chasing logo perfection.

Responding to a fan who complimented the logo for SpaceX (Musk's contribution to the Billionaire Space Race), he revealed that the swoop of the 'X' is "meant to represent the rocket’s arc to orbit." Hardly an earth-shattering visual pun, but yeah, I can see it.
