[6] HackMIT 2015's theme was experimentation, and teams built projects ranging from an Apple Watch air guitar to computer vision analysis tools for security camera footage.

Keynote speakers this year included Liz Fosslien, author of webcomic Out of the Office, and Jack Conte, musician and co-founder of Patreon.

[9] Over the years, HackMIT has seen a wide variety of hacks, ranging from new web and mobile app concepts to novel hardware/software interfaces to machine learning and computer vision projects.

In particular, HackMIT emphasizes building working prototypes rather than business plans or ideas, and participants are encouraged to be open about the technical challenges they faced in the judging process.

In past years, this event has featured separate learning and hacking days, with students at MIT volunteering to teach classes on introductory web and mobile app development.
