Prototypes and renderings
When a project involves the manufacture and distribution of materials, gadgets or other products, the creator must ensure that contributors know at what stage of development the project is.
Show your prototype.
Give a realistic overview of the project status. Present the work you have done and what you have to do.
No photorealistic renderings.
Technical drawings, CAD models or sketches are quite acceptable, but we do not allow photorealistic renderings that could be taken as a finished product.
If your project is about making gadgets or other products, describe your intentions as clearly as possible, providing, for example, a production plan, a timetable and other interesting details.
Concrete product development projects must have clear demonstrations of prototypes in operation. If it is possible to start a project around a prototype, you can not offer products under development as reward.
