I agree with tanuci, awesome idea :)

Slightly creepy in a way, but I like it.

I like this because they're tall and because they flow off the canvas on all sides (completing the illusion that there's more we aren't seeing). I think it would be interesting if the canvas was much taller, like 100x300 or 100x400, even if there's some white space at the top and only a couple of them reach more than 2/3 of the way up.
