I suposse that the use of an arduino kit (with sd or micro sd datalogger among other characteristics) and some extesometer sensor could be the better option, but i don´t know how to do it... Thanks!

hologram technology

Holograms are the most popular sci-fi device ever thought up but no one has made a actual entity that can stand in front of you. hologram progectorsfit in pockets in movies why don't they have them now. the closest thing i could find was a video; http://www.youtube.com/watch?v=pLa1rdfu6Bg my idea was to have multicoler lazer diodes that target dust particals in the air and reflect off of them to create an image or perhaps millions of nonobots that position themselves in the air obove the projecter for a more precice image. what do you think?
