Tuttle, can you do a video of your shunt climbing ? I don't get it

I have'nt video'd it, but i'll explain it.
first shunt is used as an hand ascender, with a foot loop, the croll is attached at the bridge with a bungee to upper shunt.
Now the other shunt is clipped onto my boot my laces, as foot ascender, I got dyneema boot laces rated at 900kgs....Although thats an odd one, its just a stepping device...a bungee can be attached there too, to pull everything into play.
so its a frog walker type thing.
I then use the shunt on its own with a tether to the bridge as drt setup.
Of course there are guide lines and horror stories, but care is used and there are loads of tricks to descending by bending the rope through a carabiner etc.
