First of all, I love the idea and I think it's very creative. As for my impression, but I don't think the blurry images is impressive enough to load an additional 32 kB per image. I think the UX will be approximately the same with a 1x1 pixel image that's just the average color used in the picture, but I can't test that out.

Its around 20 bytes per image, not kB.

Earlier quoted context omitted.

As far as I know just about any file format other than JPEG is better at this. If I recall correctly you basically want to go with GIF if your thumbnail has less than 255 pixels total.

just tested this and the jpeg ends up being 690 Bytes while the gif ends up being 2 KB

That can't possibly be right. What size image are you using here?

Very nice, I just saw the Ruby implementation[1]. This looks useful! Right now I'm making 16x16 PNGs and this looks way better. I might attempt making a custom element that renders these.
