I decided to hide it with a poster and so I had to make one!
Step 1: Stuff you'll need.
Ducttape (or atleast stickytape of some sorts)
Doublesided foam mounting-tape (or something to stick it up with)
High-resolution image .. I suggest using an imagesearcher like Altavista (yes everyone uses google but they ARE helping the chinese and american governments to censor the internet so I just can't support them)
A program that makes posters. Here are my favorites :
PosterRazor - a stand-alone program that makes posters from images as a pdf-puzzle. This is the one I will be referring to.
Poster Printer - a program that acts as a printer-driver to print anything directly as posters.
PDFCreator - another printer-program but one that makes PDFs from any program.
Step 2: Choose your picture.
My suggestion is to find an image that is :
Colourful - otherwise you'll run out of ink, imagine printing 1,5 squaremeters of red.
Really high resolution - otherwise it will look like crap when you blow it up.
Search with a searchengine of your choice.
Some nice places are :
Step 3: PosterRazor
You input the image where it says "Input image" and then you click on next.
Step 4: Defining paper format.
I chose to remove all the borders, ie setting them to null.
Step 5: Image overlapping.
I set 1mm overlap and bottom right . coz I wanted to :)
