Construction kits for big kids

It's a project to develop an open source hardware standard for builders, hobbyists, and anyone else who needs to create structures with lightweight, sturdy, reconfigurable and extensible metal parts. They are now in the process of raising funds through Kickstarter through October 24th. If that goes well, look for the first production runs to be done before the the year is out.
Update: Funded, with plenty of room to spare! I'm happy to be one of the first backers of what should be a fantastic enterprise.
