Let me start this guide by saying this: If you haven't beaten Myst yet, stop now. I'm not going to tell you how to get to any of these places, I assume you've beaten the game and know how to solve all of the puzzles.
Furthermore, if you want a spoiler-free version of this guide that doesn't have pictures of the secrets themselves, check out the tumblr version of this guide.[twitch-eaglehart.tumblr.com]

The first egg is easy enough. Start by raising the sunken ship. With the ship raised, there are ropes you can climb up into the crow's nest:

Once inside, you'll find a carving of Jamie and Adam from Mythbusters, as well as a Moiety dagger from Riven. Jamie was actually the one that sculpted one of the prop daggers used in the making of Riven.





The second egg is inside the fireplace. This egg was actually never completed; if you enter Hannah Gamiel's initials into the fireplace, the game tries to award you an achievement that doesn't exist, and you're stuck in the fireplace like a dunce until you load the game. It's likely this one will be patched out.




It isn't yet known how you're meant to reach the third egg: If you head out to the gear platform and look over the railing, you can see something on the beach behind the tower


If you manage to get there, either through hacks or by using glitches to fall into the ocean, you'll find a polaroid


While you're flying around, take a moment to look inside the horizontal gear on the gear platform, for a message left over during the making of the game. (No, saving there doesn't trigger anything or have any adverse effects)

Head over to Mechanical and enter Achenar's secret vault. You'll see a meat cleaver stuck into a block of wood near the door

When the little door is open, standing nearby will cause you to crouch, and you can get a good close look at the cleaver's surface. Inscribed in the reflection is a message that's very hard to see. Move back and forth a bit if you have trouble seeing it, it's in very large swirly letters.




Now head over to Stoneship. Go to Achenar's room and find his dresser

Turn the hologram on, and set it to the skull. Then, open and close the drawes in the following order, assuming the top drawer is number 1 and the bottom is number 7:
Open 4, Close 4
Open 6, Open 2
Close 6, Close 2
Once you're done, if you open the bottom drawer, you'll find a photo of Jeff Dunham and Achmed, the Dead Terrorist.



Now go to Selenitic and get into the Mazerunner. From the very start of the maze, you're going to go:
N / W / N / E / E / S / S / W / SW / W / NW / W / N
Here's a crude map. Red nodes are the normal route out of the maze. Follow the red lines instead.

Once there, you'll find a crashed mazerunner on the northwest corner

Rime's crystal imager has one solution that lets you see a screen from Riven. However, there are also 17 other solutions to the imager.
7 of them are variations of the incomplete combination in the journal upstairs, and will give you glimpses of an age (commonly called the puzzle age or the baked potato age) that was also in realMyst's imager.




The other 10 solutions give you photos taken by Cyan's developers.

The final three eggs are pretty easy to find. The first thing you have to do is get the good ending, and return to Myst after Atrus has been given the white page. Once you're back, you'll be able to find copies of three other games made by Cyan, and clicking one of those copies puts a visual filter on the screen that resembles what that game originally looked like. Clicking the copy again will disable the filter, but if you don't disable the filter it will persist through loading new games. More than one filter can be used at once, but it looks like ♥♥♥♥.

A copy of Manhole on 5 floppy disks can be found behind the clocktower on Myst Island. You can walk around the back if the wooden door is open. Clicking on them will give you a black-and-white stipple filter.

A copy of Cosmic Osmo on CD can be found inside the spaceship on Selenitic, along with a pair of fuzzy dice. Be careful, because once you leave the ship, the door closes and you can't get back in again. This disk will make the game monochrome.

A copy of the original Myst can be found in Mechanical, inside the music box next to Sirrus' throne. Clicking on this disk will reduce the game's color pallete.
