Here is a an organizer built by CLKL that makes use of plastic yogourt containers. It also uses duct tape and grommets, which you have to love. She has an excellent set of instructions on her blog.
If you have to have a mini-van, I'd say you have to have one of these. The only thing I wonder: What about binder clips? Could they have made CLKL's console better or would it be overkill?
