Preety cool

reminds me of heavy rain's interface :P
since its a demo :P heres a few suggestions

Try and make the transition between the end and beginning of the video loops end in the exact same spot and it will seem a whole lot smother for the loops.

Transition from when u click were really jumpy D: see if you can smooth those out a bit too :D

Also, clicking the links were kinda hard when they move by really fast D: slow things down just a bit and ur golden :D

Seeing a finished product that runs smooth will be awesome so i'll keep my eyes open ;)
