The Ivory Tower of Primitives is a location in Second Life that was created to demonstrate the different types of primitives available for use in Second Life and the different types of manipulations that can be applied to them.
Residents can come here to see how each type of primitive can be manipulated and combined to create some more complex objects. It is built using a lot of scripting which allows residents to change the language shown at each display as well as being able to obtain notecards from each display.
As far as I know there is no other location similar to is in Second Life so there is not really any other similar location that it can be compared to.
I feel that it is a good resource for a new Second Life resident or one that is new to creating objects as they will be able to see how the manipulations look and get ideas of how to create the objects they would like to.
