You run across quite a lot of promotional online games created for one client or another that are basically lame implementations of unoriginal gameplay that make you droop with tedium. Surprisingly, this one made me smile.
The gameplay is not exactly original; it's a jigsaw puzzle. In fact, it's not even a jigsaw puzzle, as the pieces are all squares. However, they're also not static images; a video is playing, in all the pieces simultaneously, and you have to reassemble them into the correct frame for the video.
A neat technical trick, although I've seen things like it before; the video is, however, a frantic, anarchic music video for a pretty rollicking Denver punk band called The Gamits, and in the visual chaos it's fairly hard to see what goes where. The fact that the music doesn't suck helps a great deal, of course.
What's technically cool, though, it that this is HTML5, not Flash or Unity or any plug-in, but a wholly web standards-compliant application, and a demonstration that decent web games no longer have to use proprietary platforms. (Of course, few extant browsers support HTML5 yet; you'll need Chrome or Firefox 4.0 Beta.)
If you 'win,' you get to download an MP3 of the track for free, which is both canny promotion and a nice draw to play. My only beef, really, is that I wanted to try the next level -- I want a couple of dozen music vids from different bands, here.
