I went to Motovun in Croatia for a holiday in October 2011, just as I was leaving BT and embarking on going solo in order to work on TiddlyWiki5.
Jack was a very friendly local stray who would hang around for food and affection. I had some fun taking pictures of him, ending up with this one:
The picture became a favourite, which is why it has gradually become a de facto mascot for the TiddlyWiki project. The rationale is something about a cat eating as many tiddlers as it can...
Best wishes
