Interesting, Tatiana, I'll have to do a bit of research. Never heard of indiegogo, but then I never heard of Kickstarter until this week.
Reading through the Kickstarter goals, I would think it would be easier to just go get a job than to spend all that time promoting and trying to squeeze money out of people you know.
EDIT: "Indiegogo is an international crowdfunding site where anyone can raise money for film, music, art, charity, small businesses, gaming, theater, and more."
I sorta like this one: Let's Build a Goddamn Tesla Museum
We're trying to raise money to buy back Nikola Tesla's old laboratory, known as the Wardenclyffe Tower, and eventually turn it into a museum.
