RE: Double the trouble
That is fascinating about your grandchildren @roleerob... I had a couple close friends in high school that were twins and they had the most intriguing connection, especially during adolesence when they were both wanting to discover their individuality. I had fun getting to know their idiosyncrasies and differences as well as similarities.
I wanted to play out the "fantasy scenario" of being able to possess multiple bodies and continue through to a less-than-fantasy conclusion—that eventually, some of our worst qualities would emerge, we would take having more than one of us for granted, etc. and experience disconnection.
Partially, I was being purposefully exaggerative, hopefully not too heavy-handed. Perhaps we would actually have a wonderful time having an army with the same DNA! I would expect near-telepathy and lots of unusual phenomena in such a scenario.
As for the images, I made them using Final Cut Pro, which is a wonderful video editor for Mac but doubles as a great still image editor as well.
