From Slashdot this morning...
This is really, really cool.

It's like an RSA key that doesn't require batteries and can't be given to an attacker over the phone: http://www.passwindow.com/

What happens if you have a different screen resolution/size than they expected? Then the boxes don't line up, and it doesn't work.

According to the Slashdotters, there's a CSS trick that will make an image a certain size (say, an inch) every time. Does it work with all browsers and all OSes? Dunno.

I can resize the image on my screen using control and a two fingered scroll that doesn't involve the browser at all. I can even attach two monitors of different sizes and put the same display on both. There is no way a "CSS trick" can know exactly how many pixels per inch my display is.

Hmm, I'm a bit skeptical that it'll work in many cases. It only has to be a bit off to fail altogether. I suspect the real problems would commence with mobile devices...

There'd need to be a control to adjust the size of the image.

Everything new is old :-)

It's conceptually similar to the LensLok of the mid 1980s, that was used as a way to attempt to thwart software piracy. The main difference with the Lenslok was that instead of a pattern of partial characters, it used a pattern of vertical lenses (flat ones, basically like a Fresnel lens not a magnifying glass).

It was a real pain in the arse to use, the user had to resize the image according to the size of their television after loading the game that had Lenslok protection, and if the user had a very large or very small TV it wouldn't work at all. And like all DRM, the pirates very quickly stripped the games of the lenslok code despite some very tricky schemes (for example, involving the R register of the Z80, which is used to keep count of the DRAM refresh) to prevent people from getting at the code.

(Off topic but you'd have thought games makers would have learned that DRM is useless after 25+ years of trying it, and all it does is annoys genuine customers).
