(For anyone that's unsure of what exactly a TAS is: http://en.wikipedia.org/wiki/Tool-assisted_speedrun).
Are there any of these that you've particularly enjoyed watching?
For me, it's: http://www.youtube.com/watch?v=AQ9SYw8VgjY
I don't know what to say except that it trumps itself over and over. Just... beautiful.
Edit: For anyone who doesn't feel like watching the entire video...
