I know a lot of these skills can be replicated by most gymnasts, but towards the end of the video there are a couple that are simply astounding.
First, the clip titled "HFK One Arm Coffins" is a video of Hannibal for King performing one arm front lever pulls.
Second, the last clip entitled "Half and Half" is of Zeph doing an odd muscle up in which he does a one arm chin, then puts his free hand on top of the bar and does a one arm dip to the top position. Click ahead and watch those two, it is definitely worth it.
