I learned about this at the Mini Maker Faire: Make Workspace at the Green Bay Barnes and Noble that was/is going on this weekend.
The B&N thing has demonstrations and experience some of the latest products in 3D printing, robotics, coding, programming and more.
The Green Bay Proto group appears to be in some early stages of formation.
They have also been setup at the Green Bay farmers markets trying to get some attention.
