This may be old news because I know the event has been played for a couple of years, but I stumbled across this and thought there might be others interested in learning this.
The Egg buildings from the Down the Rabbit Hole event are actual egg- or oval-shaped buildings from around Europe:
Spanish Egg - Torre Glories, Barcelona
Russian Egg - Egg House, Moscow
English Egg - The Gherkin, London
Indian Egg - Cybertecture Egg, Mumbai
Enjoy!
