Providing a so-called "BoxShop" as you mentioned would be great for many reasons:

1. USERS would get an expanded shape library much faster

2. SELLERS would have a revenue incentive to create quality shapes based on feedback ratings

3. OWNERS (Vitaly) would reap revenue from each shape sold

4. DEVELOPERS / DESIGNERS time would be freed up to focus on bigger, better things

5. ALL would benefit from a fast growing library and the expanded customer base (BUYERS) it attracts

This could be a similar model to or marketplaces.
