DHTML Arkanoid One of my favorite arcade classics, and one of the slickest applications of DHTML I've ever seen.
Triglav. It's fun, it's gorgeous, it's PC and Internet Explorer only. It's also unstable as all hell, so play career mode unless you don't mind restarting your whole game frustratingly often. DHTML gaming at its finest. (from the always excellent jayisgames, which is having a fantastic week). Triglav was previously mentioned but was as of then unfinished. If you're already hip to it, play meteor busters instead.
Behold Oddpost! Like they say, it really is "indubitably the most astounding web-based email application on earth." I was skeptical, but their drag-and-drop interface is so clean and functional that comparing it to Microsoft Hotmail or Yahoo! Mail is like comparing a Frank Lloyd Wright house to a birdcage made of Tinkertoys. All DHTML, so it requires IE 5+ on Windows. Netscape, Opera, Mac, and Linux users are out of luck. (Welcome to the effects of market share.)
3dHTML. No Flash, no nothing. Wow.
Quoth the Raven: "Buy A Ford Explorer on Yahoo!" In the category of "new and exciting ways to annoy users - I mean, generate ad revenue," the front page of Yahoo! now has a DHTML ad involving, um, blackbirds flying off a wire and eating birdseed, revealing an ad for an SUV. On the one hand, it's a clever use of DHTML. On the other, I just feel dirty.
Jesus, put some clothes on. It is always nice to see that someone is using DHTML for a healthy purpose...
Building A Great DHTML Chaser -- by Aaron Boodman. I've built one or two of these - what Aaron calls "Chasers" - you know, the little floating layer that follows you on a web page as you scroll. I was never too thrilled with the outcome for various reasons, but Aaron really put in extra efforts to resolve DHTML animation issues and came up with a fairly slick bit of code. A sample can be seen here. Whether you think they're annoying or useful, the based-on-refresh-rate animation info is still fairly useful.
Sexy DHTML Tricks Abound! Have you seen the DHTML pop-up items at PHP.net? These things are cool, cutting edge and amazingly groovy! Nice to see additional features added to the page without bloating the design. I like it! (DHTML compatible browser needed!) [ref: nublog!]
This DHTML site is just plain amazing. Hearing that the author wrote the whole thing by hand in a text editor with nothing but a book for reference is incredible. It reminds me of seeing an insane rug or quilt at a museum and hearing it was stiched by hand using only crude sewing tools. Just thinking of the work it took to make that site makes me want to cry in pain. [link pilfered from kottke]
This is probably the coolest dhtml thing I've ever seen. An analog clock that follows your mouse. Simple, but addictive. [thanks medley]
ControlFreak is a kickass DHTML site that features reader-contributed artwork, essays, and programming. You gotta love that DHTML interface too.
