• Elon Musk said Sunday he "somewhat agonized" over the font designs for his companies Tesla and SpaceX.

In a series of Sunday tweets, Elon Musk said he "somewhat agonized" over his choice of fonts for his businesses and revealed a hidden meaning behind the SpaceX logo.

Responding to a tweet about serif and sans-serif fonts, the billionaire businessman took a break from posting cryptic memes and discussing politics to say he loves fonts and put significant consideration into how his companies are presented to consumers.

"I somewhat agonized over the Tesla & SpaceX font design (love fonts tbh)," Musk tweeted. "There are some similarities, particularly use of negative space. We've made many little tweaks over the years."

The Tesla logo — a T-shaped design with a custom, sans-serif font spelling out the brand name — is meant to resemble a cross-section of an electric motor. The SpaceX logo, written in a similar font with an extended X, references the reusable rockets made by the company.

"The swoop of the X is meant to represent the rocket's arc to orbit," Musk tweeted.

Other business logos have also held hidden messages: Baskin Robbins, a chain that sells 31 flavors of ice cream, has a secret '31' hidden in the letters of its logo. Likewise, Amazon's arrow logo is meant to represent a smile, while the circular 'B' logo for Beats by Dre represents a person wearing the popular headphones.
