- Ultra(sub)marine -  
  
Before going ashore again, Rockford finds an abandoned submarine where he can earn a bonus if he comprehends the mechanism!  
  
---------------------------------------------------------------------------------------  
  
another little kind of puzzle for an intermission; this one can be tricky for the first time to figure everything out; also the timings are not so trivial.  
  
classic bd themes:   
timing (bd1-int 1)  
discovering and using a ΛΛΛ (bd1-h,o,p, bd2-a)  
  
difficulty: 3/10 (medium)  
  
--------------------------------------------------------------------------------------------  
  
thematic colour: ultramarine (255 degrees on the colour wheel)  
  
colour 0 (background): 100% saturation, 30% value  
colour 1 (ΓΓΓ): 50%, 100%  
colour 2 (ΕΕΕ): 100%, 100% (pure, "electric" ultramarine)  
colour 3 (ΔΔΔ): 25%, 100%  
  
etymology of the colour name "ultramarine": it's latin for "beyond the sea", because the pigment came to europe from asia in the middle ages.  
the name "electric u." for the pure form is a reference to bright electric lights. a few other colours are called "electric" in their pure form too (we will see some in the following caves.)  
  
oxford definition: a bright blue colour.
