A kid's idea of OS, reproduced by him on Scratch. Hope you like it. When you hit the green flag, it prompts for a password. Enter the super secure NASA compliant pasword, 'thBx5'. Voila - the super awesome KKOALA with so many (4) applications. If you want to open an application close the one you are in first, then open the next. Though I'm a frog I made the OS koala, that too with two K's.
Thanks to the scratchers for making OSs I understood how to do it. Once this reaches 200 loves I'll make version 2. Comment for version 2 changes.
