I've only ever got a hold of two shinies unintentionally in the past: During my first playthrough of SoulSilver, when I met Zapdos, it did a sparkly effect thing. Back then I had no idea what it was and since Zapdos' shiny is god awful I couldn't tell if anything was special. I did catch it, but this save file ended up being deleted because of a bad egg I encountered further down the line. Second shiny was a shiny Budew in Platinum that also ended up being deleted because my friend jokingly pulled up the "delete save data" menu and ACTUALLY accidentally pressed yes. Unfortunate, that. But it was Budew so it didn't really hit me that hard Never tried shiny hunting before. If I really wanted a shiny I'd just get one from my friend solely for the color change and not really for the 'woo, this is super rare' thing. I should give it a try, though..
