How plausible is this idea.

I had a really fun idea that I wanted to do, now that I will have a laser with a visible beam.

I know it wont be easy, and I know it wont be perfect, but since I'm strange it would be fun and look cool.

How awesome would it be to have mirrors to reflect a laser grid on your door....I'm talking horizontal/vertical grid.  I know it sounds strange, but I'd LOVE to just freak random people who walk by my door out.  I'd probably have the most issues aligning the mirrors, but has anyone tried anything like this?

or you can use a bunch of LDs    yeah the only problem with this is, if i understand correctly what you intend on doing, once they step through all the other lines will terminate     ive seen things where people will project images etc onto air like they do with water. anyone ever try playing with lasers around those air ionizers? dont know if that would do anything or not.. could always make a door from lexan or something and project it to that?
