Does your clock require frequent refilling?

Hi Henk,

At the moment its working but its not perfect. The biggest challenge i had was to make this really look like fluid and kill the ferrofluid spikes. I simply wanted to animate the fluid not make it obvious that its a ferrofluid. So i had to thin the ferrofluid with all kinds of different things, some work better some work worse, still testing.

That's true! It's not viscous at all, which makes it all the more mesmerizing.

I was wondering about the spikes. What did you do that worked / didn't work to fix that?

What is the 'thickness'? I'm guessing only several millimeters??

actually this was the hardest part, how to make numbers look thick and REAL, and connected. Here is a GIF that shows this nicely:

Thats the reason why i had to work with ferrofluid and change its structure and composition, i wanted to have thicker numbers. Whole screen is 10mm thick inside, and numbers sometimes go up to 8mm of thickness. They are especially nice from the angle because the seem like they float and not simply stuck to the wall. I will make better photos definitely.

You've done that quite well. I'm surprised its that thick, but it looks like it give the numbers an awesome rounded look.

Really adds to the organic look and feel.

Well done!

Yeah, when there is no number it turns to big blobs of liquid that actually touch walls of the screen on both sides, so i guess its bigger than 10mm in that case

I love how this is a complementary technology to 3D printing by the way of a traditional printer. Simple. Effective. The biggest obstacle for widespread adoption might be software, in other words a robust toolkit for designing "wraps" of these imprints for your own 3D models.

Well I may just be suffering from the curse of knowledge, but I found blenders texture paint system to be very good.

Once set, you can employ so many techniques with it to map images to a 3d model.

Boeing's Phantom Works reportedly tested the EMDrive years ago [1] and nothing came out of it. Edit: Thank you nether.

They haven't gotten clearance yet, but they hope to. Edit: SpaceX page indicates an attempt in July so they must have.

Maybe not as much, but Apple has been "poaching" Tesla's engineers.

Oh wow. If you follow the link to tksharpless, they have a YouTube video. I got dizzy when I stuck my nose right up to the screen. Next best thing after GearVR if you don't count the nausea from involuntary camera movement.. From further away it just looks distorted (like it should) because of FoV mismatch.

At 52km you don't need heating, and in the case of a breach the clouds would stay mostly out because of equal pressures on both sides of the dwelling. A scientific outpost, like those in Antarctica, would be highly appealing. For permanent settlement, Mars takes the cake.

Did you just explain why some people experience visual snow? http://en.wikipedia.org/wiki/Visual_snow

Wow, I never knew. I have this a a low level. Always have.

Here's a mildly interesting thing: Say you are at a stop light, and you want to get the jump on the other guy.

Jiggle your eyes rapidly around the light, and you will pick up the change more quickly than other people do.

Eyes do not have frame rates. They sample in a staggered fashion, some rods / cones, others, inner eye priority, outer eye lower priority, with movement getting priority overall and detail.
