About 15 years ago I had the great good fortune to visit a Faberge exhibit at the Portland Art Museum. It was focused on the exquisite gemstone animals Faberge produced, but there were two Imperial eggs there. Sadly, my favorite EVER Faberge critter, a snake on a hunk of turquoise, was not included. I remember one of the eggs had a miniature of a palace, all in gold, that included not just the tree-lined driveway to the building but freakin' WINDOWSILLS. All made before electricity was widely available in Russia.
And then there's this story, which was skimmed over in a documentary I just saw:

Can you imagine how hard it must've been for the poor fella not to wet himself???
