I think this is called "String of Buttons" from South Eastern South Africa, but I may have the id wrong :) Like the trailblazer you can see the object now and also backwards through time with each layer.. which makes it a 4-dimensional object* ;P
Yay! I can see in 4D :)
Better large ..
Happy Sunny Sunday to all!!!
Family : Crassulaceae
Species : Crassula perforata
*This really is a 4-dimensional object, because everything is 4-dimensional :) Us poor humans can only see in 3D .. or can we? ... *cue the Theremin*
.. come to think of it, that means this would be a 2D projection of a 3D model of a 4D object .. cool! :)
