The clue is in the second row of the tiles, the one under the statue. If
you look good you will see that they are composed of two of the left tile
(complex means two tiles of the left raw mixed).

At the start the machine is set exactly like one of the left tiles, so click
on that one(on that tile) then compose the second figure, like you see in
the complex tile figure under the statue.

When you have done the second one on the machine, click on second tile
needed for creating the complex tile on the left wall and then on the
complex one under the statue. Go on like this for all the complex figures
shown under the statue and a door will open.

This solution is probably more clear:

If you examine the tiles they are composed of the shapes on the wheels. Turn
the wheel so that two shapes are opposite and push the relevant tile. Two
tiles combined match an image on the square of four tiles. Push these tiles
when the images correspond. Keep going till all four tiles are pressed in.

George's turn
Take the torch, and ask Titipoco to light it.

Then pull the lever on the wall.

Woooooooooooo!!

Another room, now use the torch on the other one on the right of the room.
