If you’re at your Mac, go ahead and click a window for another app (don’t forget to come back right away). Clicking an app’s window brings it to the foreground, of course. But did you notice that only the window you clicked came forward. If that other app has any other windows open, they will stay hidden. It wasn’t always this way. In pre-OS X days, the default behavior was to bring all those windows to the front. And now, thanks to a new app called Front and Center, from John Siracusa, you can get this behavior on a modern Mac.

Many people can’t bear to part with their old computers, and slowly build a collection of aging models in their basement. Benj Edwards took that impulse to the next level: He owns at least 228 unique devices, many of them classic Apple products going back to the 1980s.

Now he’s put them all up for sale. Ready to start your own computer museum?

Aakash Doshi is a third-year student at the Srsihti School of Art, Design & Technology in Bangalore, India, and he has a wonderfully hobby: he distills Apple’s Mac line-up down to their essence in bright, colorful, beautiful abstractions of their classic designs. I love them. We’ve put more after the jump, but be sure to check them out in hi-res on Doshi’s Tumblr, where he’ll be adding more over time.

I’ve always had a little crush on Susan Kare, the graphical interface pioneer who designed most of the original Mac OS icons and also designed the first proportionally spaced digital font, but this incredible piece on her over at PLOS had me wooed all over again, especially when I saw her incredible original sketches of the Mac OS icons we all know and love, which Susan laboriously designed on graph paper.

Check out some of her work on icons both familiar and foreign below, it’s the best thing I’ve seen all day.

This is a huge hack: a plucky modder has resurrected a Macintosh SE/30 using a Seagate Dockstar, a small Linux server running a 1.2GHz ARM processor, a few USB 2.0 ports and 128MB of RAM. Not only does it work as a server, but in runs a Mac emulator, and even the floppy drive works… but it reads SD cards mounted on a floppy-shaped protoboard instead of ancient 5.25 discs! He even restored the Mac to pristine condition by bathing it in chemicals to return it to its vintage, unyellowed color. Amazing!
