Looks pretty nice, but isn't actually that complicated. He just moves a background image ( http://labs.dragoninteractive.com/panel/demo/lib/img/form/ma... ) around all the time, and only let a small part of it shine through.


As anext step one you could use webkit animations to make it js-free.


That's really clever.


Anyone else think that this JPG is more like an animated GIF?


It's not particularly hard to do these kinds of things with a bit of imagination. This is our demo from 2005, unzip and run index2.html: http://www.pouet.net/prod.php?which=18327


It's a webpage hosted on a webserver. Can I just view the webpage with firefox please?



That kills my CPU. I'll be sticking with <canvas/>.


Parts of that are <canvas/> I believe.


That's pretty fun!


As I expected, it also takes an Amazing amount of CPU. Also, the caret flickers like mad.


Agree with the CPU. But I'm on FF 3.0.10 on Win7 RC and there is no carrot flickering.


Additionally, you can log in with labs @dragoninteractive .com and password demo


That’s inspiring. As bemmu said it’s not difficult, just takes some thought.


I see only a login screen.


Click inside one of the inputs (login/pass) and watch the border of the form.


Truly amazing, no matter how easy it is.

Simple is beauty.


Just look at your CPU spike though... not so good for netbooks or phones.


the lab start-page (http://labs.dragoninteractive.com) is even more worse. it's funny to have the task-manager open and watch the CPU usage while clicking through the site. poor, poor CPU
