As one of Vuo's developers, I work on Vuo's engine (the thing that makes compositions run), work on nodes, and write documentation. You'll see me on the forums answering people's questions about Vuo.
I've been developing apps and frameworks for several years (since I was in college). Pre-Vuo projects include Kineme Quartz Composer plugins, iOS apps for education, an app that analyzes photographs of tomato slices, and software to help people with disabilities use talking keyboards.
I enjoy using Vuo to make live music visuals. My hope for Vuo is that it will grow into a community of people of diverse backgrounds and identities making lots of different artistic, useful, unique, goofy, beautiful, crafty, wonderful compositions.
The hard work, dedication, and collaboration of 45 performers from the London metropolitan area culminated in four performances of the stage production Hyper. Hyper had multiple purposes: to provide an evening of entertainment and culture for audiences and to showcase the artistic and musical work of the performers, all of whom have learning disabilities. A highlight of the show was a dance piece in which performers painted projected imagery with their body movements, using skeletal tracking and graphics technology that included Vuo.
First answer — Yes, as you figured out, Alastair (@usefuldesign), Re-Fire Event fires an event through the trigger port or input port that most recently had an event manually fired. (This is mentioned in the manual under Firing an event manually.)
