These look amazing! And, wow, yes, some of these are more polished than a lot of big-name commercial plug-ins are.
I'm still happy to see the unpolished ones, too -- as I said, I think it reveals something about thought and work processes (and, of course, it's the way most of us use the tool).
I find I'm designing some ensembles specifically for Kore or other control, so that it's not as huge a deal what it looks like -- actually becomes more important to label nicely for the Kore controller. But I do like things that look great on-screen, too. I've seen some other examples where Reaktor is just a back-end sound engine and people build full-blown projected / tangible interfaces / Processing sketches, etc., so that's also possible.
I did get a couple of additional submissions via email. I may get more once I put it up on the main createdigitalmusic.com page, probably in a few days, though the gurus are all here on the forums.

As far as the easiest way to send things:
Flickr is probably best, just because it keeps the photo and description together and such. I've also done some programming with the API, so I can easily bring up views of all the shots.
http://flickr.com/groups/reaktor/
I know not everyone uses Flickr, though, or has a pro account (and that it's been controversial for moves in Germany specifically). So whichever method is best. The pictures (at) createdigitalmusic.com account is working fine, too.
Posting here works, as well (nice that the forum makes those cute thumbnails). So wherever you like; I'll put them all together in a week or two. It'll be interesting to see everything side by side.
