Haven't you always wanted to carry around a paper shredder in your pocket?
Haven't you always had the need to virtually shred things without damaging the actual thing – therefore not actually accomplishing anything?
Haven't you always wanted to augment your reality in pointless ways?

Fret no more!

This super-special demonstration exemplifies the pinnacle of machine vision and augmented reality: To tackily recreate an artist's stunt from late 2018.

This is a one-trick novelty of zero value.

Enjoy.
