A few months back, I started learning to program with Flash. I was excited about the work and directions of my friend and associate Tom Saunders, and I wanted to engage with some of the questions of user interface design and data representation that had long inspired me. The core language of Flash -- ActionScript -- has a common lineage with JavaScript, a language I learned to love in 2006. One of my first Flash programs was a hacked-together proof-of-concept for accessing Drupal services through Flash remoting/AMFPHP. That was November 2007. Four months yielded a great deal of productivity for the Drupal/Flash project: internal, the introductory talk at Drupal Day, Andrew Haeg, soon a new site for The Hobo Nephews of Uncle Frank band, as well as some very interesting r&d from Modern Carpentry. Today I am very pleased to post the first of a new set of iterations for arithmetric.
