Fascinating that this camera ball snaps the pictures when it is at maximum height and has the least movement which prevents ghosting effects. Seems that it only works, or works best when thrown upward to achieve this inertia point. Perhaps this is a prototype that, like all things techy, evolves into something amazing over time.

"Panoramic image stitching can create panoramas from pictures taken one after another [but] acquiring the images takes a lot of time and moving objects may cause ghosting. [Also] the downward picture cannot be captured while the camera is mounted on the tripod. In this work, we present a throwable panoramic camera that solves these problems."

The ghosting isn't caused by the objects moving but by the fact that the object have moved between frames. This ball takes all the frames simultaneously so it doesn't need to be stationary to work except as needed to minimize blurring of the exposure. So, assuming a well lit area and the device having fast CCD capture you could take pictures with the ball in motion.

Gaz is an Iranian candy made of nougat with pistachios. It is often served in cakes the size of thick cookies and coated in flour to keep it from sticking to everything. It is also sometimes found wrapped like hard candy.

most science majors get to do this in lab, and it's dece, but on this scale it's awesome.

oddly, the guy in the video calls this "quantum levitation" and talks about "locking", which i'm pretty sure is the wrong way to describe it. anyone care to expound?

i can't find any literature referencing "magnetic levitation" as "quantum levitation", but oh well, i guess it sounds more viral (OMG VIRAL, LIKE BUTTON, DERP).

for anyone interested, some more info: en.wikipedia.org/wiki/Meissner_effect
and
en.wikipedia.org/wiki/Flux_pinning = "locking"

regardless, this is the best demo of this effect i have seen.

such a cool phenomenon.
i haven't read enough to say why, but I think that this is indeed different from the Meissner Effect so they may be justified throwing "quantum" in there.

Quantum Locking is what happens when you expose a super-cooled superconductor to a magnetic field. The super-cooled semiconductor allows the magnetic field thru only at certain weak points called Flux Tubes. In this way, the superconductor material can be 'locked' into a particular position in the magetic field.

FYI - I posted a link in my re-recommendation that shows a larger experiment using quantum-locking.

I love my EVO 3D. Making 3D videos and pictures is fun and watching 3D content really takes you there. It's amazing to see.

This is a tiny, lightweight weapon but don't let it fool you. It's not a .22, it's a .380 (9mm). I carry this comfortably concealed almost everyday.
Cons: No safety and long trigger pull. The sites are fairly useless but it's designed to be a short range weapon and Crimson Trace makes a nice reliable laser site for it so you can just point and click.
