First brief video ideas

For my music video I would like to have a mixture of narrative and performance set around a house party. A boy and girl are shown both getting ready for the party which is shown in the first 50 seconds of instrumental music. By the time the lyrics start they are both at the party and fall in love over the course of the song. The two band members follow the protagonists in the video whilst performing the song without them seeing, inspired by Look For The Woman Video. In the end the protagonists walk out together holding hands and so do the band members.

To capture the surrealist vibe of MGMT videos I would like to project images over the bands faces and the party as a whole. These screenshots are taken from the video Doubt by Delphic and capture the effect I will be going for. I would like to get patterns from the effects used on windows media player which already follow the beat of the song. Actually producing this effect will be difficult as I will have to look into using projectors attached to a computer or look at doing it in post production.



Checklist -
Actors
- Band - one girl, one boy
- Protagonist - one girl, one boy
- Extras for the party, will try to show only select angles so it looks like more people are there than there actually is.

Sets
- Two bedrooms for the protagonists to get dressed at
- House for the party

Props
- Guitar
- Keyboard
- Party clothes and smaller props can be gotten easily
- Digital projector (?)

EDIT-

I have been looking into how to create a digital projector effect without actually having to use one and found this: http://tinyurl.com/3y5cmo6 which looks very useful but I will have to look further into this and see how it works and if I could create one myself using a computer instead of a television.
