On the Subject of Peekaboo

Something’s wrong. I can feel it.

This module has six spherical buttons, each with seven properties:

1. The colour of the button.
2. The colour of the border of the button.
3. The 2-D shape on the button.
4. The colour of the boundary of the shape.
5. The colour of the interior of the shape.
6. The symbol inside of the shape.
7. The colour of the symbol.

When the module activates, the LED will begin flashing as its sensor detects the defuser. Rotate the bomb so that it is facing away.
After three seconds have passed, the LED will stop flashing and the sound of a bell can be heard.

Rotating the bomb back around will reveal that one of the buttons has changed one of its properties.
Select that button to deactivate the module.
Selecting any other button will cause a strike.
