Always wanted a poster of something cool you saw?
Here's a simple how to.
Take a pic of whatever you like.
I for instance saw this newspaper add of this girl and HAD to have her on my wall.
So I took a phone pic:
Then went to http://homokaasu.org/rasterbator/ and downloaded the program.
Now open any picture you want, choose a size(I did a 3x3 a4) and you get a printable PDF file.
All that is left to do is print the pages and stick them on your wall.
