Sounds about right. They actually already have this setup, the T2 chip in recent macs contains an arm processor which handles some tasks like disk encryption. It could be possible that future OSX versions will leverage that processor for more general purposes.

I think i was a bit too optimistic. I would load 5 iframes at once with 2 either side of the currently selected one. It was much quicker but I couldn't find a nice way to reduce resource usage; I think the browser still attempts to compute all those animations even when offscreen. Setting the dimensions to 1x1px for offscreen frames didn't do the trick; I tried going down to 3 and that still ended up in lots of CPU/RAM usage. I think it's probably do-able but would require some more tinkering.

BTW: I like your mobile/tablet previews. I was actually going to do the same but left it out for the moment :P

Oh nice, themebeacon seems much more comprehensive than themefinder.

For the speed issue; I was playing around with an idea of preloading the iframe previews to speedup loading; it worked but the browser would crash due to high CPU/memory usage eventually. Maybe you'll have better luck?

Just hit the arrows to the right / left of the preview, you can also use the left/right arrow keys to navigate.

You can browse the site and add/remove wallpapers from you collection with one click.

Also you could upload your entire wallpaper collection, to the site and then remove them from your collection, only keeping the wallpapers you want to see at any one time. It's useful if you've got a lot of wallpapers and a limited dropbox size.
