It is just a simple bag, the exterior design is to be a layered triangle tessellation that can be expanded and contracted. I was imagining wooden triangles with a mesh material sandwiched in-between. The bag would have an adjustable carry strap and some padded compartments (like a laptop bag) inside, and a zippered opening.
I would like some nice 3ds renderings of the expanded and contracted bag as well as technical diagrams or wireframes of the bag and it's interior and the strap.
I anticipate the bag would be around 900mm long x 600mm high x 400mm wide.
