Basically, a thread for the things you might consider awesome you would have done in your life.
I've learned how to replace/add computer hardware from the inside of the PC at 10, and once the queen came to a city swimming pool, to mark a grand opening, i was one of the few people invited there, while she was standing on the balcony with her husband, i did a salute and she waved back, i thought it was quite rare :o
Anyway, what's your cool stuff?
