Idea of using bitcoin for large group projects

[J1800]

I've been addicted to certain warcraft 3 custom maps for 15 years and I've always liked the thought of paying 12 people a small amount of money to play a map with me at a certain time (especially nice if they all speak English and agree not to d/c), and wished someone would develop a platform like this. But it could be used for other things. Let's say I wanted every object in the British museum photographed. I'd upload some money to the platform and then decide how it gets shared out to each user who submits such photos to me. Maybe there are other ideas where one could pay large groups of people small amounts for a collective work project?
