In the future, rather than just saying "failed", it will be more helpful if you explain exactly how it failed.
When I tried it, I got compilation errors in Photo.as that the gs.TweenMax could not be found. Googling "gs.TweenMax" led me to the page
http://www.greensock.com/tweenmax/
where I downloaded greensock-as3.zip. This Zip file contained a SWC, greensock.swc, which I added to the project's 'libs' folder (alongside the Alternativa3D SWCs). This didn't fix the compilation error, so I checked the catalog.xml file inside greensock.swc (which is just a renamed Zip file) to see if there was a TweenMax class inside. There is, but it has been renamed to com.greensock.TweenMax. When I changed the line
    import gs.TweenMax;
in Photo.as to
    import com.greensock.TweenMax;
it compiled and ran. So there were two problems:
1. The Alternativa libraries are relying on a free Greensock library that you needed to also have. (This was probably explained somewhere on the Alternativa site.)
2. The Greensock library that Alternativa is expecting appears to be out-of-sync with the one available on the Greensock site.
