Motivation behind Zoetic
I lived next to a building site for 18 months and, from the start, decided to take regular photos of the construction's progress. I took just less than one photo per week. I did not carefully set up each shot. The only constraint was that I took each photo from the same window of my flat. I had assumed that by the end of the construction I would be able to easily find a program that could stitch the photos together to create a movie of the 18 months. When I discovered such an app did not exist (or at least one that didn't require a lot of effort) I decided to create one.
