My brother and I have been working on http://rukus.io http://rukus.io for the past year. We've gone from a super simple linear rendering proof-of-concept to an architecture that scales to millions of renders/month.

This has been one of the most enjoyable and rewarding things I've ever done despite having to make some serious sacrifices. Even if we don't succeed financially, my personal growth has been reward enough.
