Kind of Bloop: An 8-Bit Tribute to Miles Davis' Kind of Blue

I remember this, as indeed they say, it was one of the very first Kickstarter projects. Kickstarter did a good job of seeding the site with cool artistic projects. I think this - and the fact that they only allowed creative projects for a long time - was what made it work.

Others had tried the same idea (Pratt and Helm's "Fundable.org", no relation to what's currently on that domain), but they had serious problems with project quality and credit card fraud.
