I don't see this as a MP4/WebM replacement (compared to which it is effectively inefficient) but a GIF replacement (plus it's scriptable and hackable in a number of interesting ways). I wish it were a real, self-contained file format, but APNG completely failed to displace GIF.

It's a hack, but it solves a real problem and it opens a venue for something less hackish.

Also, it's simple enough any developer can understand the algorithm, there's no patent looming over, no complex codec infrastructure (however layered away), and it's using only HTML/CSS/JS.
