There's nothing illegal or inherently wrong about using Kickstarter to fund a theme or a music project. It actually makes sense: Time is precious, and a lot of people have jobs, and family obligations. Why shouldn't they turn to a community of like-minded people to keep things moving? I generally like to keep things free (I don't charge for my give-aways on my blog), but sometimes you just can't work without a budget.
Now I don't theme (and I hadn't planned on posting anything about my project, and I really don't make it a point of asking for $ on this forum). That being said, I use Kickstarter, and maybe this will help point people in the right direction in terms of how to post a project and start getting funded:

And if this violates some forum policy, I apologize in advance. Just delete it from the beginning so that the ending can't be heard.
Cheers,
