Since there's a thread for Pokéradar and Soft reseting, why not one for obsessive egg hatching?
Check here for details. Basically, you take two Pokémon from games of different languages and breed them and the chance that the offspring will hatch shiny is 1/2048 (4× the usual rate). This method makes it easier to get shiny Pokémon with egg moves. I'm not completely sure but I've heard that the Everstone will not work with this method, meaning that natures won't be passed on.
So, what shiny Pokémon have you caught with this method and how many eggs did it take?
I obtained my shiny Chikorita on my 171st egg.
IN GENERATION 5 ONLY:
The odds of getting a shiny with this method are now 6/8192 (6× the usual rate). The Everstone now works on natures so you can pass on natures with foreign Pokémon.
