'Dear Google,' said I, 'please show me what a shear crack in sea ice looks like.'
'Do you mean T. Griffith Taylor's unpublished stereograph of the shear crack between Inaccessible and Tent Islands, which he and Wright admired on the day Wright wanted to shoot Teddy Evans (who he thought was a penguin), which is probably why you're searching for shear crack reference?'
'Why yes, Google, that will do nicely, thank you.'

Hey everyone, I've created a video that shows how I make a shifting 3D effect animation from my 2D artworks using Gimp!
✦ Written guide below the break ✦
I'm using Gimp 2.10 on Pop!_OS
Open your image in Gimp.
Create a new layer over the art, color to black, and lower the opacity.
Starting with a dark to medium gray color fill in each element, working from back to front, visualizing the figures in a 3D space. Black is the background, white is closest to the front.
When your gradient map is complete, move the layer underneath the artwork and go to Filters➺ Map➺ Displace.
In Aux Input double click on the gradient map.
I personally prefer to work in Horizonal Displacement only, so I have to click the little chain link icon to the right to “break” the chain and allow only one axis to be displaced.
It doesn’t take a big shift to make an interesting effect, in this video I only move the artwork 2 degrees in each direction.
Here I displace two images total to create a perfectly looping four frame animation. Frame 1 shifts slightly to the left. Frame 2 is the original unedited painting. Frame 3 is shifting slightly to the right. The final frame is just a duplicate of frame 2, to create a perfect loop that goes: 1 2 3 2 … 1 2 3 2 … etc.
Make your animation! You can open all frames in Gimp to export as a GIF. Note that with your animation layers in Gimp, frame 1 is the bottom-most layer, going up from there.
For this video I simply opened the image files with my video editor Kdenlive, shortened each frame to 00:00;05 seconds, and made the loop that way.
Thanks for watching, let me know if you try this with your own work!

Native people, by definition, are intricately connected to the land. And there is no more indigenous native people than Palestinians. [Palestine] is at the intersection of continents. Even birds – 500 million birds – pass through Palestine on annual migrations from Africa to Eurasia. Humans also migrated through this country. So actually, those of you who are not African, you are Palestinian because you came through Palestine when you went out to Europe and other places. This juncture of continents also was important historically, because it was the first place that humans went from hunter-gatherer to agricultural communities. This happened about 12,000 years ago in a place called the ‘Fertile Crescent’, which includes Palestine. This is where we first domesticated things like wheat, lentils, barley, chickpeas… hummus, you must have had hummus. Even in the Bible it says “the land of milk and honey,” right? So it has never been a desert, so to speak – it's a very rich, beautiful country.
They lived in relative harmony with nature for thousands of years. Scientists and archaeologists and so forth describe this area as the beginning of so-called ‘civilisation’. Because hunter-gatherer [communities] couldn't support a large number of people – they were mostly nomadic, running around to where they could find things to eat and drink and stuff like that. Whereas when we became agricultural communities – [when we] domesticated plants and animals – we settled down, so population could grow, and we could have things like villages and towns. And that's why we find, for example, Jericho is the oldest continuously inhabited town on Earth. In these 12,000 years, once we had agriculture we had time on our hands, so communities started inventing things like religions and art and music and law, and the alphabet was invented here. That's the beginning of civilisation. And we as Palestinians are very proud of being part of this history. – Mazin
