This is a cool little program. I think you can do this with photoshop, but I found ythis to be way easy. Imagine making wall sized art from a normal printer. The Rasterbator Page

A friend of mine showed this to me a couple months ago. I made a 24 page picture of Bob Marley and put it on the wall at work. They didn't really appreciate that.

Sweet, I am playing with a lot of ideas right now. I will post a pic if I come up with anything I think is worthy.

I have used other special software for poster printing. It makes good posters.

P.S. I understand that it is not new thread, but I think this link will be helpful for forum community.

Rasterbator is great, I like it! It creates images from large dots. It is an interesting art technic, but when I need to print exact enlarged image.
