I know virtually nothing about yoyo tricks, and found it damn impressive. He moves extremely quickly and very accurately. That level of skill takes years of practice!
I didn't read the description. Now I cannot hear :)
We used to have these "EXTREME YO YO" groups that'd come to our elementary school assemblies and they'd do all sorts of tricks. I learned "Walk the dog" and could do a few tricks but kids started hitting each other with them so the teachers banned yo yos. I know, this sounds exactly like the Simpsons episode. But maybe it was a common thing. Anyway this was awesome. I should have stuck with that instead of DDR which for a while made my legs bigger than my torso.
