The story of how Ron Avitzur and Greg Robbins created Apple's graphing calculator is pretty remarkable.
The projects they were working on at Apple got cancelled and they were laid off but since their staff passes still got them into the building they kept coming in and working unpaid.
"Why did Greg and I do something so ludicrous as sneaking into an eight-billion-dollar corporation to do volunteer work? Apple was having financial troubles then, so we joked that we were volunteering for a nonprofit organization. In reality, our motivation was complex. Partly, the PowerPC was an awesome machine, and we wanted to show off what could be done with it; in the Spinal Tap idiom, we said, "OK, this one goes to eleven." Partly, we were thinking of the storytelling value. Partly, it was a macho computer guy thing - we had never shipped a million copies of software before. Mostly, Greg and I felt that creating quality educational software was a public service. We were doing it to help kids learn math. Public schools are too poor to buy software, so the most effective way to deliver it is to install it at the factory.
Beyond this lies another set of questions, both psychological and political. Was I doing this out of bitterness that my project had been canceled? Was I subversively coopting the resources of a multinational corporation for my own ends? Or was I naive, manipulated by the system into working incredibly hard for its benefit? Was I a loose cannon, driven by arrogance and ego, or was I just devoted to furthering the cause of education?
I view the events as an experiment in subverting power structures. I had none of the traditional power over others that is inherent to the structure of corporations and bureaucracies. I had neither budget nor headcount. I answered to no one, and no one had to do anything I asked. Dozens of people collaborated spontaneously, motivated by loyalty, friendship, or the love of craftsmanship. We were hackers, creating something for the sheer joy of making it work."
