Pretty much stuck on the code behind the artwork. Not much to go on.

NVM: Out.

Good for you. I'm trying to figure out the grey box with the warning sign on it.

Never mind, found out you

find the CD at the edge of the rug, the piece of paper on the table, and the pen on the shelf, trace the CD onto the paper and put it in the grey box in the slot above the danger sign.

I can't seem to find the pen...

[Genghis]

Edit:

look to the left of the danger box

Stuck

I guess I need a hint for the code... I have

Blue, Green, Yellow glass balls and rubik's cube

Now what?

Out -with lots of help from EG24

[NannaJoy]

think we need one more ball. Back today to give it another go.

cube - next to green would be white then Navy & yellow. Top red and bottom orange. Not sure if that will help or not.
just noted RaeBob went off to find help and left me not a clue.

1974 - year cube came out

bgyr

Some debate on where that came from
out but not on my own.
