At Twilio, they believe code is a creative endeavor that allows humans to amplify their intent and potential. The company's SIGNAL conference aims to bring this philosophy to life by providing developers with hackable tools and environments to express themselves creatively. By giving attendees access to hackable swag, such as the Hackpack badge, they encourage experimentation and innovation. The response of the attendees was impressive, as they quickly deciphered how the system worked and pushed its limits, demonstrating that code is indeed a creative tool.
