I really like the idea of making everyday objects into computing devices/holders for computing devices. For example, I have a set of 5 vintage American Tourister suitcases [1] lying around, and I think they would make for awesome suitcase computers.

For this movie bag, it would be cool to see some more modifications. Maybe sew in a laptop sleeve and accessories pouch to make everything fit better?

Neat! You could cosplay a 1970s fictional president, carrying the "nuclear football".
