Ahhh the grid, I remember that. There was another highly touted company around the same time that also had some mildly interesting tech and ideas sort of in the same vein but just burned through VC money. I was hoping the grid layout system based on constraints would mature enough to become a proper css standard at some point. We did eventually get css grid, which is pretty good, but having a constraints solver in css would be pretty neat. (Or just a performance nightmare.)
