Step 1: The Template
What it contains:
- 2 portals in orange and blue. They have a transparent background that has to be replaced with the pictures from step 2.
- 2 Portal logos. One is bigger than the other one, I cut the letters out and glued them under and over the portals, this looks a lot more professional ;)
- A nice picture of my favorite cube, the Companion one! I just don't like the feeling of wasting space, cut it out or throw it away, I don't mind.
The template is available for a white and a (dark) brown background, because the boundary of the portals are blurred. The picture down there shows what it looks like, but please don't use this, because it is way too small.
Here you can get the template in both colors:
Step 2: The Pictures
Step 3: The Marriage
This is what it should look like:
Step 4: The Poster
I ordered the size 150 x 100 cm, so the portals are ~100 x 50 cm big (In fact it's a bit lower but wider)
That should cost about 30 - 40 $ (please mind the forwarding charges).
Step 5: The Time Until Your Poster Arrives
Step 6: The Physical Work
Attach your portals flat on the surface you want to be portaled, that works best when you use 5 - 10 pieces of double-sided tape, 2 of them in the middle and the rest close to the boundary. First, only use the 2 pieces of tape on the top to fix it and see if it hangs correctly. Then you can fix it with the other tapes.
Step 7: The Finishing Touch
If you also want the GLaDOS-camera on the photo, this is just a papercraft and can be downloaded here: http://paperkraft.blogspot.com/2008/03/portal-papercraft-security-camera.html
I assambled it with 155% of the size.
And now you're done! Have fun with your portals.
