@cozmicray: LISA started as a design challenge after I felt bad for telling someone on this forum that lead screws are a horrible idea for column deltas. It was mostly a joke. I never intended to build it. My students happened to need a project and everyone seemed to like the concept so I threw caution to the wind and let them build it. For me, that is the end of it. I have shared the idea and the files and it is up to the community to carry LISA into the future.
LISA is inherently bad because any error in the straightness of the screws will be doubled because of the rotation and could be even more than doubled if you go for high speed rotations. It was a fun concept but it doesn't fit in my value engineering vocabulary.
