Questions on the Interface...

I got through this reading aiight - even though it took forever to comprehend... and aside from some general questions about the purpose of this chapter, i think i understood most of it... but my 2 questions are:

• What does "meatspace" refer to?

• What is an example of a temporal composition, if temporal relates to time?- if thats even what temporal relates to.

[What would be an example of content preexisting interface anyway?]
