Well, his creativity has been corrupted by his granddaughters! And now he is writing Apps for fiction, Mad-Lib style creations of stories that are personalized. It's easy and fun. Just enter content into the fields and press download story. Check it out:
Here are his words from his Linkedin post:
"This is nothing to do with work. Girls don't tend to have exciting (geeky) stories written about them. I wrote a large set of helicopter rescue stories for my granddaughter Ella, then another set where she flies an anti-gravity ship (invented by the Professor) to the moon, Mars etc. With her permission, I've now put the text on-line in a way that you can enter the name of your daughter, granddaughter, family friend and immediately get a fully personalised version as a Word document.
You can then have fun adding your own illustrations (a key part of what Ella and I did together). The early stories are very simple because they were made up on the spot. The later ones needed lots of research before telling them. The final helicopter story is a blockbuster expedition on Everest and the anti-grav trip to Mars features all the big sites on that planet. They are currently only in English (Ella is German but bilingual) but in principle could be translated to other languages if anyone wanted to help."
