The basic idea is that you take a comic, break it apart panel by panel and splice it together in an animated style, sometimes having a character actually make a subtle movement. Music, sound effects, and even voice overs may be added to heighten the effect. Distributed online, or in some cases on a small disk the new format has some interesting appeal.
I personally rather enjoy the branching off of styles, granted it's not well suited for all story types. Though arguably the Hentai community will do well with it, they do well with everything...which is sorta disturbing in it's own right, but like the porn industry- actually may periodically take a new approach to something before it catches on with the more mainstream, viewer friendly aspects. I'd personally love to see more of this with manga, currently it's most often fan made- something I think groups like Shonin should jump on. HA see what I did there, because they are called sh- oh you already got it.... A great perk to this too comes from the ability to distribute to a broader audience. As it stands now, most manga fans who are up to date need to go through scanners and other fan translated and hosted sources ( and I actually feel they do a much much better job and presenting the true series and dont “ honey coat” the text for a generic western market aimed to be more kid friendly.
