Ask HN: Basecamp for Art and Code

I have a 3Dgame project starting up. I had used basecamp awhile ago and was very excited to hear they had a new rev. Sadly, I was very disappointed to see that there is still no proper integration for artwork. I think there is a great opportunity for a startup to create a basecamp like product for artists and designers, with image roll-over, audio/video support, and vector art. And also have it link out to Github. Maybe there is a product but I sure haven't seen it in my research. If anyone has suggestions it would be greatly appreciated.
