One of my somewhat recent projects I worked on completely in Flash was a “YouTube widget” in which I created a video carousel that adheres to the specifications given by YouTube that reads the XML feed for each of 6 our channels though the XML parser I wrote would read any YouTube feed. They do require that you use their embedded or chromeless player which we ended up just going with the embedded player. I’m very excited about this project and take a bit of pride in how it turned out.
