City of Illusion

Someone at the local shopping centre has done these rather cool pictures, that pop into 3-D if (and only if) you stand in the right place and take a photo. From the side:



From the viewpoint:



Here's another:



I'm not sure why they all have to be pictures of bloodthirsty animals committing vandalism, but I suppose it shows the technique to advantage. The strange thing is, though, that even if you stand in the right spot, the illusion doesn't work unless you take a photo. Then, everything pops into place. Of course, I can't show you how unconvincing it is if you don't take a photo because to do so I would need to... well, you see my problem. So, you will have to journey to Bristol to see for yourself - and Bristolophile though I be, perhaps it's not worth doing that specifically to fail to be convinced by an illusion. I do find it interesting, though. Presumably the addition of a frame cuts out all kinds of peripheral information that our brains involuntarily use to detangle what we see?

Or, you can come to the Cathedral and look at the moon that's been installed there, which is also kind of cool.



Or even take part in a Wallace and Gromit Fix-up-the-City augmented reality game. That's still on my to-do list, for when my daughter gets better after her bout of what-might-possibly-be-COVID-although-the-tests-keep-coming-back-negative.

Here, nothing is what it seems.
