[64] 4 ball multiplex box fun

These box like and busy patterns feel good to juggle as well as being easier than the 'normal' 4 ball boxes. 

First pattern is ([64],2x)(2x,2)* then some ([64],2)(2x,6)(2x,2)* which I learned as [64]6121
The two patterns here are similar but feel very different, both classics.
