Displaperture: Bringing the Rounded Corners to Leopard
Ah, aesthetics, aesthetics. Apple, you’ve made me a fiend for aesthetics. You gave me the Genie effect when I minimize a window, and translucent menus when I need to open a file. But when you created Leopard, you made a bunch of changes to the aesthetics that I used to love so much.
Some of the changes I like, and some I can live with. But in Leopard, you took away my rounded screen corners. Well, thanks to the Apple developer community, the guys over at Many Tricks have brought back rounded screen corners with their application Displaperture.
The application weighs in at 169 KB, so it certainly has a small footprint. It runs as a process rather than modifying specific files; for system modification chickens, this is a blessing, but a curse for resource hogging fiends. You must keep the application on your drive for your corners to remain rounded.
Users can adjust how much their corners are rounded, and which corners will be modified. Furthermore, you don’t have to round all 4 corners: you can modify just the upper corners, the lower corners, the upper right one and the upper left one, or any other combination that you desire.
Displaperture is freeware and can be downloaded from Many Tricks.

Okay I’m a sucker for aesthetics. Installed!
I think the move to proper corners was a good idea – form FOLLOWS function, and with round corners, there always was that “No man’s land” between the curve and the corner of my screen.
Seriously, I think filling out all the screen estate was one of the better decisions concerning the new desktop.
