I'll start it off with Cascade, the 14 minute flash video that ended Act 5 in Homestuck. No, you don't need to read Homestuck to go "...wow, that was pretty cool" as I've tested this on my boyfriend and a roommate, both of which don't read Homestuck.
A tl;dr of the video: bad guy kills some people, does an ultimate attack! 3 of the four kids achieve what is called God Tier in their game session, and Jade is just badass with her Dog Tier status. No, not God Tier. Dog Tier.
So now that I've christened this thread, post moar videos!
