After playing Portal, I needed my very own companion cube, but didn't want some cube cluttering up my desk. So after spending some time in the hobby store, I found a nice cube shaped tissue box holder, and thus my useful companion cube was born.

What you'll need:
Cube tissue box holder (this is not a plain tissue box since tissue boxes will need to go inside of it)
Silver high gloss spray paint
White high gloss spray paint
2 Cereal Boxes
Pink Acrylic paint
White acrylic paint (for touch-ups)
Paint brushes
4x 2 inch wooden disks (can be found in Michael's, Hobby Lobby, etc)
Hot glue gun
Extra hot glue

Step 1: Base Paint and Pattern preperation

Take your tissue box outside and spray paint it with the gray/chrome spray paint.

While that dries, print out the pattern and cut it out.

Cut along the edge of your cereal boxes so that you can open them up and lay them down flat.

Trace the pattern 8 times on the inside of the cereal box. You should be able to get 4 on each box (2 on front, 2 on back). Add in the score lines.

Go outside and put a second coat on your tissue box.

Guys, do you know how long I have been waiting for half life three? Almost 5 years! I do not expect that the second I stall net comes out soon. When (if) it comes out I will be over the moon but for now focus on completing your OWN valve games
This looks great! Very much like the companion cube! I just wish I could find the cube-shaped box though =/
There's gonna be a portal 3!
Please do not talk about the ending I havent beat portal 2 yet!
i heard there going to be a portal 2
there is going to be a portal 2. i heard it should come out sometime in october 2010, or later in the year. they will introduce new features like the Personality Sphere, Excursion Tunnel, Aerial Faith Plate, the Thermal Discouragement Beam, Pneumatic Diversity Vent, Repulsion Gel, and Propulsion Gel. not to mention a multiplayer option that leads you on a completely different story.
I heard it too.
I also heard that. Possible with the next installment of The Orange Box.
that would be sweet
Yeah i heard it as well. Does anyone know when orange box 2 will come out, and what games will be in it. Cos iv'e already got the orange box and i don't want to buy the same games twice.
it might be called the black box not orange box 2
It won't be called the black box because  it was supposed to be like a "collector's edition" but the idea was scrapped...
That sounds cool. cant wait for it!
these take forever to make! it seemed pretty simple but each one, (tracing, cutting, and gluing) took like, 30 minutes. at least they look cool
No cake box used in this sigh !!!I want cake!! Great Job !!! I didn't play the game but I did watch my kid play it and it was interesting enough that I may have to try
the cake is not a lie. you have to finish the game.
he's right, at the end of the game the girl/robot tries to kill you when you find a way out and theres a room with like a million cakes on the shelves."the cake is a lie" is from all the other subjects who found a way into a sideroom and wrote it on the wall
There is only one cake, and "like a million" robot parts. And the robot's name is GLaDOS.
what are you talking about? did you finish the credits?theres a room with alot of cakes on the shelves "WIKIPEDIA" The final scene, after a long and speedy zoom through the bowels of the facility, shows a mix of shelves surrounding a chocolate cake and the Weighted Companion Cube. The shelves contain various metallic "eye" components similar to GLaDOS' core chips, some of which begin to light up before a robotic arm descends and extinguishes the candle. The credits roll, and GLaDOS delivers a concluding report about Chell: the song "Still Alive",[18] in which GLaDOS sings "I'm doing science and I'm still alive." "WIKIPEDIA"
I have NOT finished the game yet it is spring break here and my son has NOT been off the games for 2 weeks ...I can play when he is at school I think
You Should be able to play it while he's away, because I beat it in 1 hour.(30 minutes to beat the chambers, but I like to goof off...a lot)
You pretty much proved his point. "The shelves contain various metallic "eye" components similar to GLaDOS' core chips, some of which begin to light up before a robotic arm descends and extinguishes the candle."
Yeah, like the Wiki entry said, &quot;shelves surrounding <strong>a</strong> (singular) chocolate cake.&quot; The shelves contain &quot;<strong>various</strong> metallic 'eye' component<strong>s</strong>&quot; (plural). &quot;A robotic arm descends and extinguishes <strong>the</strong> (singular) candle.&quot;<br/>Lots of robot pieces, one cake.<br/>
NOOOOOO!!!!!!!!!! I was stuck in one level and just got it finished and still have lots of game left to play now I guess I will bake a cake and cry into it .....oh well I will finish this game and then bake my own cake
***SPOILER***: True, there is cake. But, you don't get cake as mentioned at the beginning of your training. It's in the cinematics at the end, but not in your stomach...=(<br/>
I did finish the game and I did see a cake but alas I didn't get to eat it .....
i ate the cake (it was sharp and crunchy), and now my computer screen doesn't work. :)
After testing is done you will be baked, and then there will be cake
actually, not to be pretentious, but the cake model itself is hollow, and you can run right through it, almost like a hologram. in the end, the cake is a lie.
lol stop glitching in there, and all of our hopes will remain.
the cake wasnt a lie. the LIE was that GLaDOS would share it with you...
SAY IT AINT SO !!!!!! Oh well I still want to try the game but my son is always on the orange box for the X-Box ....maybe I should get a box of cake mix ....I did like the way you could see yourself through the holes in the wall first game I have seen in a while I want to try
you should play Portal for sure, it rocks.
I just started I had to use cake to lure my son away from the X-Box
no its a pic on the wall
Playing it when son is at school or on his computer but I am stuck in a level and son WONT help me ...I may have to ground him for a week if he don't help ..lol even if he does I should so I can finish the game ....your right it rocks
There's no sense crying over every mistake. You just keep on trying till you run out of cake. And there's science to be done and you make a great gun for the people who are still alive. Aperture Science
And when you're dying I'll be still alive And when you're dead I'll be still alive Still alive...
Still Alive.
Still alive.
Dont spray paint it silver, because the companion cube is NOT silver. Its dark grey and the dimensional corners arent white, they are a lighter grey.<br /> This project took ages!<br />
holy crap thats cool
This is teh greatest
Quote from portal: "Maybe you should marry that thing since you love it so much. Do you want to marry it? Well I won't let you! How does that feel?" OMG FAVORITE GAME EVA!!!!! I HEART U CUBE!!!
what exactly is a companion cube
google Portal ;)
i did. this looks like a really wierd game, but very challenging
