Watermines
I built 20 watermines in a row, near the Karnak CS. They don't really work but they look cool! Some of them are are mostly in the sand and the spacing isn't uniform, but still, it was a fun project.
Special Hookah
I won a special hookah at a Reflection tournament. Ajars (aka Dors) had even come back and played in the tournament. We would have tied for highest place but his game lasted just a few minutes too long (he won it though). The hookah goes by the names "Elephant Ears" and "Fire Hose Hookah" and I think it's unique in Egypt. It is right by the Karnak CS and usable by the public. It is something like 8.7k quality.
Lightboxes
I got a couple of lightboxes, a sapphire and an amethyst. I bought the sapphire one from Ahz but I can't quite remember where I got the other one. They are by the anvil building.
Compounds
I built the anvil, shark, ship, crab, and bird compounds, near Karnak CS. I also helped Aberdon with his wine shaped Good Eats compound. I'll have to do a total count of resources spent on them, off the top of my head I think it was about 15k cut stone. I also had the blue oval compound but I gave it to Ahz for his gem museum.
Gem Museum
The shark, ship, and crab buildings have my custom gem cuts. The ship has 46 tables, the shark has 28, the crab has 23. Total number of tables is 97. The crab has my favorite cuts. There are also a few cuts that other gemcutters have donated, they are labeled with a chest. Unfortunately some of the tables in the ship building are too close to the chariot stop to build chests on!
Torches
I have 50 colored torches lining the road between my compounds, near the Karnak CS. Unfortunately it is a pain to light them and they go out after 10 hours, so I rarely do. And if you set them to public usable, people can reposition them! Still they look pretty nice when they are all lit and you look down the road.
