1. Is the grid/tron system populated by of programs from the ENCOM computer cloud/system or is it only made up of programs that Kevin Flynn and his various alumni created?

2. If a program is meant to look like their user, why dont all programs in Tron city look like Kevin Flynn? (Do programs like Beck and Zed look like their counterparts? Kevin claims he programmed Dyson himself?)

3. In Tron: Uprising, are there any meanings behind the secondary smaller circutry colors? 

4. My most baffling question. In the ending of Tron: Legacy Is the entire grid wiped out?

Someone plz help.
