Move to the panel that is one to the right of the gold SIGIL picture safe puzzle. At the lower left of this panel is a small contraption. Insert the flywheel here. Slide both switches at the same time to show a drawer. Open the drawer to get the camera light. Described as “some sort of device for reflecting light”. This drawer contains a secret hidden panel! Tap the back part with the square to get the hexagonal piece of map. Insert this map piece into the big globe to get the brass winding handle with a square pin.
Attach this light device to the TOP part of the teleporter from earlier. The light will not attach to the lower area, only the top area. This will reveal the meter.
What do these buttons below the light do? Well, you need to press the right button, zoom out, find the newly opened button at the top of the table in a similar position to the first buttons. Press that button, then zoom out again. Then find another meter button. Press that and finally get a piece of map.
A star shaped piece of map. Tibet, I think. Insert the star shaped piece of map into the big globe.
Now return to the light meter with two pentagon buttons. Press the left button this time. Zoom out, rotate, press another meter like before. You will eventually find a brass key with multiple folding parts. I wonder where we will put this. Nerdr.com walkthrough and guides.
Find the big side panel with the cross keyholes. Insert the cross key into the panel. Each part of the cross only takes one key. Two of the keys remain at the lower part of the key. Pick up another small reflecting device. Add this other small reflecting device to the laser teleporter.
Enter eyepiece view mode and move the sliders on the sides until the laser hits the lower left. There are many positions so try not to get stuck here. Solving this puzzle will reveal the starlight and you get the oddly shaped piece of map. Part of South America. Attach South America to the globe.
Move to the golden circle with a nice picture and insert the brass handle level into the square hole. Rotate the handle to show a wooden circle. Enter magic eye view and align the image. Remember you can rotate the central part of this puzzle too. The top is fixed, so align the rotatable puzzle part with that. The prize is an intricate wooden box.
Tap on the intricate wooden box in your inventory now. At the base you can rotate the yellow and white cross to open the wings of the box to make a star shape. Insert this star shape into the star hole on top side panels of the table to reveal a telescope for looking at the stars!
Look through the telescope and you will see a pattern.
Move quickly to the panel to the left of the big globe and enter those lights into the puzzle piece. You get the square piece of map and a letter.
