Thank you Anders! I really like your idea, that's awesome!! The interdisciplinary team is exactly what I meant when I thought about this idea. Also chatrooms and 'google doc' will be helpful for team members' communication and team management.
Inspired by your virtual simulation idea, I am also thinking about the combination with virtual reality. Team members could preview the materials on a projection screen in the air, they could manipulate these materials by dragging and shifting. When they finished prototyping, they could get the instant result through a 3D printer, that will be really cool~
