Marrakech took the hypermedia concepts I explored in WorkSpace and applied them to the problem of managing workflow and assets for multimedia development.

WorkSpace was an interesting application that took user interface ideas from Andy Hertzfeld's Servant, and hypermedia ideas from all over, and combined them into a personal information manager that used the web of links between entities to represent meaning. It was never released as a product, but was where I first started creating ZooLib, and formed the basis of Marrakech and ultimately of Measurement in Motion.
