The numbers are backward for English-speaking countries, which I find interesting, but I'll reference them based on the numbers I see given:

17: I like it. It's a bit of a double-edged sword though, as sometimes people pause videos to not be distracted, and that sort of flickering back and forth would certainly distract me if I still had the window visible.

16: cool

15: This would be interesting to integrate with what happens when you actually click a link and it's still working on getting there, especially if you pulled your mouse away from the link before the actual page had resolved in DNS (I think that's when the URI changes on link click? I'm not sure, honestly and that's an assumption)

14: Neat trick and very pretty

13: I like how the length of the arrows increases as the system processes. As long as it's not an indeterminate progress bar (I don't know how that would be represented in this model, but that doesn't matter since it doesn't have to be), that is a beautiful way to do it. I like it.

12: I like it, as long as you could start typing during the animation. I don't like having to wait.

11: standard. good. I like it.

10: It could be useful

9: If that's what the client wants, then that's great! I certainly think it's cool.

8: I'm a bit conflicted with this one. On one hand, it's a neat trick, and exploding out at the same time as shrinking in (in the center) looks nice; but at the same time, it might get a bit old? I dunno.

7: I don't think this is rendering right on Chrome... it either has a very long animation loop, or I'm not seeing the whole thing? The button kinda gets a boil around it somewhat, or part of the way? My computer may be slowing down when trying to render it.

6: This looks like a lot of ones that already exist except more animated maybe? I find it interesting; but, I think my OCD would get frustrated since the change happens /after/ I get to the place I want to be, not at the same time. I'd end up jabbing the down or up button longer than intended. Eh.

5: there's a lot of circular activity in these options. I think I would prefer to see the button just grow in all directions at the same rate and disappear where it wasn't finished, if I were going this route; but, I'm not sure. It's okay, and something I'd tolerate if a phone OS already had it, but not something I'd add myself.

4: I don't know what this is meant for, so I can't comment

3: I'm going to guess there is a text box that would grow to the right side of this icon? I like reusing the icon as both a start search and stop search. Very nice.

2: It may just be my machine, but the graph line changes speed. I don't like that. Is it going at the same speed just laterally, making the line seem to speed up since it has to cover more distance for the rises and falls? If so, then that's okay I guess? It still feels hasty and upsetting.

1: I like the spinner. Could it just be 2 rotations instead of 3? Oh, I get it, grow, be one size, shrink. Nevermind, 3 is fine. I wonder what it would look like if it were extend to its proper size at the start of its first rotation, make a whole rotation and then shrink. I wonder how that would go. I like how it is right now, though :)

All in all, some cool ideas, many of them useful :)

[As an aside, 7->0 don't seem to load on Firefox 36.0.1, so I had to look at them in Chrome. I'm not sure why it wouldn't work in Firefox.]
