Walkthrough:
------------
* Click on right stand, and pull out the piece on the left. Remember 
  that color combination. (Green Blue Pink Red)
* Click to the left and look at the monkey statue. To the right of the 
  pedestal is a “colorful thing” that will turn out to be ink. While in that 
  same  screen, click to the back of the pedestal for a keycard.
* Click to the screen to the left and look at the picture titled “Blue O-Kid”.
* Zoom in and swipe the keycard in the reader. Take Monkey Plate.
* Click on the chair. Then click behind the back left leg of the chair to find
 the pen. In your items, double click the pen, then click the black bit to turn
 that end of the pen towards you. Then click the ink and then the back of the pen.
* Now with the colored ink pen highlighted in your inventory, click on the Colors
  box sitting on the chair. Click the squares on the top so that code matches the
  color combination from the stand by the elevator. 
* Take key.
* Go back to the screen with the monkey statue, and click on the bottom left 
  side of the pedestal. 
* Put the monkey plate into the niche. There are now lights coming out of the eyes. 
* Move two screens to the left so you are looking at a picture titled “Prime Numbers” 
  Note those numbers. (3123)
* Move back to the screen with the elevator and use the key to unlock the numeric 
  pad. Notice that there are no numbers on the keys and there is a “” on the display. 
  This is a configuration number. Zoom in on the number poster to the right of the 
  elevator. This poster is showing the different positions of the numbers on the 
  keypad at different configurations (the configuration numbers are the big green 
  ones behind the other numbers). The keypad starts at the 0 configuration. So the
  first number in the code, “3?, is in the normal spot. The configuration number 
  will increment by one every time you put in a number. So for the next number look
  on the 1 configuration. You can see the next number “1? is at the bottom right, 
  where the “9? typically would be. Do the same for each of the numbers and get 
  the following sequence: press normally for “3?, press where “9? would be three 
  times. Then hit “ENT”.You are out
