Their examples look amazing and pretty. But. Good luck trying to use them, though. They're very delicate, and break unless you make sure to find all the relevant CSS and cruft around them.
Definitely not "plug and play".
Looks cool on my desktop but does not work properly on my Nexus 7. Tapping an image does animate the text and brightness of the element, but the white mask does not move anywhere. The tap also causes the page to scroll to the top instantly.
The jump to the top of the page is just because the demo doesn't link the images to anything. In a real-world situation, you'd likely associate a URL with the href, or implement some other behavior onclick.
Cute but I thought we collectively outgrew animated hover effects in 2007.
Oh well I guess we'll never really grow up.
Its just someone showing tasteful hover effects.
Grow up :)
Well, it's not really like there's anything wrong with animated hover's as long as they're done well (as with all animation). I do like that you said "we" - it seems less condescending that way.
