Plugin/ Component Identification

Hello All,
I found this tutorial video for modeling the famous Shigeru Ban structure, but it does not specify the plugin or component that was used. Can anybody identify it, or suggest something similar that I may mess around with? Thanks in advance! Video is here: https://www.youtube.com/watch?v=Qh83kVmGAkc&index=3&list=PLVk71QLjaA6MhlFF8OapHCGxAyeloS6Pe

I don’t think it is a plug-in, look like a script component because it has an out output. Contact the person who made the video.
