OMFG, look at this shit!
 

What's that site that allows you to print out an image as individual pages and then merge together on your wall like a poor baster without enough money to pay a print shop?

I had another site back in the day, but here's a new one:
http://www.blockposters.com/

rasterbator is another one:

That's it, thanks
