This is the major egg discovery so far and is credited to Dan'ni. The clues can be deciphered in the following way:
Palindrome shapes: A palindrome is a series that is symmetric back to front or right to left. For example, "radar" is a palindrome word; 12321 is a palindrome series of numbers; and ©®¶®© is a palindrome series of symbols. The "shapes" refer to the crystals that appear in front of the Rime Age viewer. Conclusion: A combination of crystals that is symmetric right to left (first suggested by Razathar.)
Reveals sunnyside up: "Sunnyside up" is a way of serving eggs. Conclusion: This will lead to an easter egg.
But only when gassed: See Rime gas.
commencer with primero farbe pareil: This phrase, drawn from four languages (French, English, Spanish, German, and French again) literally translates to "Begin with first color same/similar." A theory was proposed by RockSunner that the color could refer to the colors of the flags of these countries. The one color that is the same/similar is red. "Primero" refers to the first crystal. Conclusion: Begin with the first crystal (the short one) in the color red. Setting all the crystals this way gives what can be called the Easter Island egg, first discovered by buckminster.
I-90 exit falls in center: I-90 is a highway that originates (in the eastbound direction) in Seattle. Approximately 27 miles east is an exit that one can take to Snoqualmie Falls, a local landmark. One of the crystals bears a strong resemblance to the falls. Conclusion: This crystal should go in the center, as suggested by Dan'ni and shadow1 (and this connection may also have been suggested in Face Chat the night of the message).
I395 US1 to independence guards the center: I395 travels from Virginia to Washington, D.C. At the Potomac, I395 merges into US1 and both cross the Potomac on the 14th Street bridge. US1 splits from I395 and continues north, crossing Independence Avenue. From this intersection, the Washington monument is a short distance away. One of the crystals bears a strong resemblance to the monument. Conclusion: This crystal should go on either side ("guards the center") of the center crystal, as first noted by Reinbag and myself.
Putting it all together: Put the short crystal in the first and fifth positions, the Snoqualmie falls crystal in the center, and the Washington monument crystal in the second and fourth positions. Make them all red, and you get the Face Egg. You can also start with all crystals magenta. And you can change the colors (carefully!) to cycle through the Cyanegg.avi file. Also, the egg will disappear if you make too many mistakes, such as triggering the egg and then changing a crystal other than the first.
