This last weekend I spent a ton of time with Unity3d and the uniTUIO project.
One of these days I will figure out how to cross-post to all the various blogs and things I am currently contributing to, but for now I will just throw some links out there:
There is the link above, that goes to the initial blog post.
http://xtuio.com/blog/2009/09/06/more-sneak-peeks/ is a post about the two layout managers that are ‘done’ so far.
http://xtuio.com/blog/2009/09/07/unittuiomolecules-project-now-with-more-movies/ shows the newly added movie support and the content switching buttons.
In any case if you are into the multi-touch surface thing, then go check them out. Otherwise, you can safely ignore them.
