Edit: did we have 1280x720 digital video 12 years ago?  The quality of the video fragments is very consistent through the video, though supposedly there was 12 years time difference between shooting them.
1080p has been around for more than that.
Cryptocurrency has taught me to love math and at the same time be baffled by it.

Cryptocurrency lesson 0: Altcoins and Bitcoin are not the same thing.

Am I the only one that noticed the chewed up belt in the early part of the video ?

You can see a couple pictures later that the pulleys and belt had been upgraded. There must be a lot of pressure between those rollers to require that much torque to make them turn.

Right before the cover is put on you can see the other motor with a narrow belt leading to the bottom of the frame. It looks like it's purpose is to drive the out-feed roller.

About that back cover, there is a clear window in it. You would be able to see the battery and wires inside the frame via that window. Not to mention that the slot at the bottom of the frame is also clearly visible.

The video does not prove much though, there may be copycats fabricating all sorts of things for fun. Certainly the person either had no knowledge how to use soldering iron or it is all part of the prank.

Edit: did we have 1280x720 digital video 12 years ago?  The quality of the video fragments is very consistent through the video, though supposedly there was 12 years time difference between shooting them.

Agreed, while 720 was available, the rehearsal segment around 2:35 taken in vertical 16:9 has only been a thing since smartphones introduced it about five or six years ago. There wasn’t even an iPhone in 2006, and the first iPhone wouldn’t even take video. The first smartphone able to take 720 video was released in 2009.

We also need to take a look at the means available to the artist in 2006, while he could undoubtedly resource this now, his income would not have realistically funded this back then, let alone the means to record this at such good definition.

The slit for the shredded version is very close to the back of the frame, but this doesn’t seem to match the various video claims.

Then there is the vertical registration mismatch. The slit exit is about an inch behind the picture. When I aligned pictures of the unshredded version to the half-shredded version, you’d expect there to be a significant discontinuity due to the additional depth offset going past the roller. That discontinuity isn’t there when you compare various reference points.

At the end the thing gets shredded entirely in one take. :wtf:

It's all a load of bollocks.

Needs an x-ray image taking, but then we wouldn't be able to spend all this time speculating!

I am. There must be rollers inside the frame to roll out the canvas. The real shredding mechanism is a series of pizza-cutter style blades adjacent to one of the other rollers. There is no additional challenge in placing that into the frame vs just rollers without the cutters.

The blades look exactly like the blades in an office paper cutter.

Seems pretty obvious to me that the thing in that video is real. Faking it would be an awful lot of work.

The only lie is that it's been dormant for 12 years.
