The brain-curdling eldritch horrors and the third dimension

Question

We're in the year 2016 so it's finally time to take puzzles to the 3rd dimension!

So let's see what those beautiful times bring us today:

Everyone of you clever sods could as well have a look at the real thing
(please give it some time to load).

PC controls:

• Hold left mouse button: rotate cube
• Mouse wheel: zoom in and out
• Hold right mouse button: move cube parallel to screen

Mobile controls (tested on Android and iOS):

• tap: stop automatic rotation of cube
• 1 finger: rotate cube
• 2 fingers: zoom in and out
• 3 fingers: move cube parallel to screen

The cube shown above appears to have, like most cubes, 6 faces of which each one carries a more or less mysterious entity. After decrypting all of them we should be able to find out what this is all about!

Answer 1

These form a rebus-like clue.

1: U-turn
2: flat (British synonym for "apartment")
3: binary for into (interpreting tall cylinders as 1 and short cylinders as 0)
4: wire
5: frame

So the message is...

"turn flat into wireframe". Doing that on the URL given lets us see a chest inside! It lines up perfectly with the magnifying glass and contains the number 5106 in it. Also, the room itself (the "flat") has the words "PSE ID" in it.

So the solution is...

Avigrail himself! He's user number 5106 here on PSE.

Answer 2

I think that others have found the answer and not realized it! They're just missing the meaning of the faces.

Here's the breakdown of each face as others have already found:

1: Turn (turn arrow)
2: Model (architectural model of a room) <<< This is the one others are missing
3: Into (Binary. Short Cylinder = 0, Tall = 1)
4: Wire (a literal wire segment)
5: Frame (Picture frame)
6: Look Here (Magnifying glass)

The key that others have missed is that the message tells you to...

Change the model into a wireframe model by changing the URL from

to

Which reveals the secret interior!

Zooming inside the model (back in solid form for visibility), shows the treasure chest:

Zooming in more lets us read the secret message of

5106 (Avigrail's user ID number)

Answer 3

The hint says

You can count to six right?

Well I can and I've noticed

There is a number on each face

1:

The U-turn arrow

2:

The living room/lounge

3:

The cylinders (@Deusovi point out its 'into' in binary

4:

The wire

5:

The picture frame

6:

There isn't actually a number that I've noticed but the last face left is the magnifying glass

EDIT:

@Deusovi points out that going inside the box leads us to 5016. The magnifying glass probably is telling us to zoom in

Putting it all together

I think we'll end up with a 6 word sentence:

You turn life into wire frame 5106. (Or something like that)

You turn from the U turn, life from living room, wire frame from the wire and frame, into from the cylinders as binary and 5016 from inside the box. Need to fill in the gaps though to make it make sense :/ (thanks for help from @AvikMohan!)
