An animated hexagonal tiling of a shape with interesting symmetries. The shape is achiral -- its mirror image in 3-D is identical after a rotation.

[Broken link: A brief description of the elemental shape, including a GIF animation of a single element.]

Modeled and rendered with Space Software.

How is it that this piece isn't yet in the M-C-Escher-Style gallery?

Happily, that's an oversight that's quickly correctable.

Ha!
I faved you back.
thanks.

you have some sweet 3d anims.
does space output these?
Reply
:iconmarkdow:
Yes, it makes a series of renderings and can output as a .avi file or serial images. But there are memory limitations, so only for short animations.

I noticed you have a lot of MRI-CT data on your web site, do you work in the industry?
Reply
:iconmarkdow:
I do work with MRI, functional imaging studies in cognitive neuroscience. That got me interested in volumetric visualization software, and that has gotten me interested in other volumetric data sources, like CT and cryo-EM reconstructions.

nice, so can you tell me what MEG stands for?
Reply
:iconmarkdow:
Yes,magnetoencephalography.

"...an imaging technique used to measure the magnetic fields produced by electrical activity in the brain via extremely sensitive devices such as superconducting quantum interference devices (SQUIDs)."

Basically electrical currents to to cortex neurons cause very small magnetic field changes that "leak" through the skull. These can be detected, and their timecourse, matched with the task that people perform, tells you something about how the brain is active during that task.

Spot-On old chap.

Nice to meet another Bio-Geek

See...
I believe that all of this great technology is only being used to a fraction of it's potential.

I was raised by a microbiologist/geneticist and after studying AI, went back to my first love, Biochemistry.
Then about a decade ago began to study vedism and Immortality.


If the use an MEG to map out the epileptic cycle, then I want to bring in a Saddhu, baseline him while we explain what we want him to do, then have him stairstep the levels of consciousness all the way to samaddhi.

just have him perform his normal practice while we record hundreds of times and keep adding instruments until we run out of signals and hidden wavelengths to pick up.

he could even guide us.

Gee... I don't want much...
of corse that would be on top of vitals and blood chemistry.
then let some super computer choke to death on one grand image.
