Skeuomorphism is a design where there look of an object used for a function is copied in a tool performing the same function.

Like early electric lights where made to mimic candelabra, lemon juice is put in a container in the shape of a lemon or the ‘call’ button on a smartphone has the icon of an analog phone on it.

In the latter case there’s a word thing going on. With the telephone as with the floppy symbol on the save button, there is a point where more people have never used the depicted object. There is a certain point in time where the symbol is used longer than the actual thing.

If that’s the case, can we still call it skeuomorphic?
