What is this?

Can anyone tell me what this is, who's working on it and if it is complete or ever will be completed? I've tried searching but have next to nothing to go on.

The sky looks awesome and gives me that same strange feeling I got when looking out of the window on the original when I was 6!

It was discussed here, where some people thought it might be from DoomDS.

Looks like Quake converted to Doom to me.

Thanks. Fascinating though quite disappointing if its only some example...

On further inspection it is a video for some proposed port of Doom to the DS.
