It also depends on your location / country, 100K gives you a lot more runway in my country than in the U.S.
Since you're a "college grad" on HN I guess a software-based startup is your goal.
Personally, I'd bet on the Oculus Rift, the guys I knew that struck it rich rode a wave of innovations / new hardware (for example the iPad), I believe the Oculus will open a lot of new avenues (virtual shopping, virtual sightseeing, virtual training, data visualization, virtual everything :) ). 100K might not get you very far in the U.S. however.
Non-software, there are plenty of franchises that give an interesting return on investment.
Do you want a business you can run yourself? Maximizing revenue? A "safe bet"? Passive or active investment?
