Gamma, Gamma, Hey!...
Loved that Lytro© photo system mentioned earlier, mutable depth of field, neat! - but here's the one we all want - a light driven time cloakWe see events happening as light from them reaches our eyes. Usually it's a continuous flow of light. In the new research, however, scientists were able to interrupt that flow for just an instant.
Other newly-created invisibility cloaks fashioned by scientists move the light beams away in the traditional three dimensions. The Cornell team alters not where the light flows but how fast it moves, changing in the dimension of time, not space.
They tinkered with the speed of beams of light in a way that would make it appear to surveillance cameras or laser security beams that an event, such as an art heist, isn't happening.
...
Using fibre optics, the hole in time is created as light moves along inside a fibre much thinner than a human hair.
The scientists shoot the beam of light out, and then with other beams, they create a time lens that splits the light into two different speed beams that create the effect of invisibility by being too fast or too slow. The whole work is a mess of fibres on a long table and almost looks like a pile of spaghetti, Fridman said.
...
The science is legitimate, but it's still only a fraction of a second, added City College of New York physicist Michio Kaku, who specialises in the physics of science fiction.
"That's not enough time to wander around Hogwarts," Kaku wrote in an email. "The next step therefore will be to increase this time interval, perhaps to a millionth of a second. So we see that there's a long way to go before we have true invisibility as seen in science fiction."
Gaeta said he thinks he can get make the cloak last a millionth of a second or maybe even a thousandth of a second. But McCall said the mathematics dictate that it would take too big a machine - about 29,934km long - to make the cloak last a full second.They think they have to build a bigger one, when probably all they need to do is link it to a strobe around 7 cycles a second, or whatever our 'reality frame grab refresh' is create the illusion of continuity...
Grant Morrison has some interesting ideas on reality related matters as well...

Hard News: Nobody wanted #EQNZ for Christmas, in reply to linger,
Don't go back to Chchch...
so, basically he’s setting up the tourism marketing angle
“Christchurch: it’ll rock your world”.The overseas travel bloggers are getting a telling off from Mr Parker and the local tourism folk as well...
Parker was not surprised by the contents of the blog but said there was "a lot more to Christchurch than what it makes out".
"It is disappointing, but to be realistic, the quake was a major international event, so it's to be expected," Parker said.
He said the blog ignored the way the city was fighting back from the quakes.He doesn't seem to understand that tourists won't want to come here to see 'how we are fighting back' - they may have enough respect to leave us to get on with it and come later when things quiet down (or, deity-willing, stop!) and we have a viable city to offer them...
my suggestion for a new city promotion caption is:
"Christchurch, more than it's cracked up to be..." -
Foliage.
That looks especially mint at full sizeSucculent, even...
Hmmm, is that food blog competition closed?

Unrepentant Marryatt...
this is a better link, from The Press itself
- better photo plus the avalanche of comments...*...unwilling to take a bath it seems

Reductio add attachment...
how do you reduce the image size
in the absence of a photo editing program perhaps one could email the photo to yourself, and reduce the size of the photo when sending, there is usually a full size, medium, small option - worth a crack...

we are plugging on...
I would be happy to come to any sinkhole site and record it .
They are trying to eat cyclists now!

Art easin' well...
...doesn’t seem to have progressed beyond this state of affairs...
I loved this bit of forward planning
(or unplanned obsolescence):The ceiling in our large foyer needs replacing (its tiles were made in Scandinavia, and they and the systems holding them in place are no longer available).
Buy Local in future!!
(though admittedly, that's no guarantee of a business, or its proprietary devices. still existing a decade down the track...) -

Pond er Russ...
Also, goldfish ...
so you're not just being Koi
or Carping on about it, then...
:- )ay, there's the rubus...
Discovered two little waxeyes who had found a
way into my raspberry enclosure this morning.A good caning would sort them out...
Time for whacks!
Sighs.... -
I wonder if animated gifs work on upload?
Nick Fury back before he was black…
(I love that Jim Steranko’s post-Kirbyian style…)
if it doesn’t work try here<!> hey, they do - excellent!

here's a coupla random photo side trips for your holidazedification...
