I have release the source code for the “Season’s Greetings” from Taodyne. This can give you an idea of what XL can do today. In that video, which is rendered in real-time and in 3D, the XL program executes 60 times per second to synchronize the animations on the screen with the background movie.
In other XL-related news, I’ve been working on an updated language reference document. This describes where I want to bring XL, notably the type system and library. A lot of what is in this document is not implemented yet, but it will give the directions that I intend to follow in the coming months.
