I presented an overview of the Sydewynder application to Sven Travis's Creativity and Computation lecture class today. I've attached the PowerPoint and PDF below (and an OpenDocument presentation can be posted, if anybody wants that).

Also, I've released Sydewynder 0.1.1, which has the option to take screenshots of the apps as they run (useful for putting together the presentation) and a new "Round Robin" sample app that shows how to send a single SMS messages to multiple recipients and multiple messages to several recipient lists.
