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.
I don't have a very good answer for your question about timeframe for fixing the graphics-related crashes, sorry. For the past several months, we've been working on features/fixes that were originally planned for Vuo 1.3 and releasing the smaller or more self-contained ones in the 1.2.x versions. Since the graphics changes are complicated, they're still planned for Vuo 1.3. I expect that will be some months away.
