Ask HN: Grants for artistic or scientific projects

Hi there!

I am curious to hear other peoples experience with applying for tech grants for products that are not growth or monetary in nature, but could still prove useful as either an exhibition of technology for a company, or as a tool for students/the public.

Are there avenues to search or apply for these sorts of things?

E.g. I have a project that am 50% done with (as far as my skills allow), but would need a small grant to complete the project. I have high belief in its potential to be highly functional and quite beautiful. It would be appropriate in universities, computer museums, and in home. How do I get someone to listen to what I have to say, short of coming up with "funders," given that there is little to no immediate monetary value?
