To both her and my knowledge, there hasn't been any projects that have attempted to be financed through crowd-funding. Though it is an interesting avenue, as there are many potential things that could be discovered (or hypothesizes tested) for less than $10k. But getting enough attention on such a campaign and interest generated could be hard without a lot of star power attached to the project.
Why do you think it ends such an age? If anything, our access to both information (via the internet) and tools (as the prices come down) is increasing. As well as more and more fields seem to be making lots of interesting discoveries (for examples, look through the FB group I f$%king Love Science (but spell out the curse)).
