This is also going to be huge for 3D scanning: https://youtu.be/sJgK0jjd6oE?t=188 https://youtu.be/sJgK0jjd6oE?t=188

If you liked this, you'll probably enjoy this video exploring how to turn a sphere inside-out: https://www.youtube.com/watch?v=OI-To1eUtuU https://www.youtube.com/watch?v=OI-To1eUtuU

  I watched this in a science museum display ~25 years ago. Was so confused at the time. Also though of it while reading this article's abstract.

Here I was hoping it was going to be more research on even more superhydrophobic surface textures.

  I thought the same, but that was sufficiently weird.

    I almost thought he had an extreme dislike for the Microsoft tablet PC's.

  First though: anti-grav.

Keenan Crane has been doing incredible work in this field for the last few years. I'm following his work avidly.

Fascinating and well narrated. I'm no math wizard but I found the explanation and illustration easy to follow. And the title of the video, "Repulsive Curves and Surfaces", is sure to draw some attention from the sheer amount of jokes it begs.

  In my opinion it's a bit over-the-top of them to make such an elaborate commentary on your mother and I'm not sure what spurred it on, but nonetheless they do deserve some credit for the effort.

  Some of the generated shapes are definitely kind of unsettling and "repulsive"!

I was blown away by this presentation. Shared widely yesterday. We are test driving the code for possible use in pangenomic modeling of genomes of many individuals—-complex genomic graphs. Some of these methods may also have good applications in neuroimaging segmentation-—the brain split into non-overlapping regions and fiber tracts that should o”not intersect (at least in our models).

  Where's the code?

  Can you elaborate further on this? Are you talking about reconstructing fiber tracts from DTIs?

So if we take the extruder making Cheetos and add a large static electric charge to it, can we have snack food in these shapes?
