I think the clues might be simpler than we are making them. It certainly was for #4.
Clue #1 - Fire? End of Tetris was launching, End of MIR was burning up in atmosphere.
Clue #2 - Water? 3 sets of Coords (presumably) = 3 points = triangle. The leo connection might be related to the Last Supper and the chalice discovered in the Da Vinci Code, which is also a symbol for water. "Deep Blue Something" = "Deep Blue Sea"? Btw, thanks for getting "Breakfast at Tiffany's" stuck in my head Thalin... The bright stars seem to correspond to where evony employees work and may have been there for clue 4.
Clue #3 - 5 rings on olympic flag? These may symbolize the 5 elements we are looking for.
Clue #4 - Solved. We got 2 more elements, Air and Earth, but what does it mean to have your name raised higher than all? Is there going to be some type of leader board?
Clue #5 - I see the symbol for Aether or Spirt in the image as a faint circle, which completes all 5 elements if I am right about #1 and #2.
I've spent quite a bit of time chasing clues on this, but not near the time Krazy, ImInsane, and some others have. I hope you guys get them and hopefully something above helps.
