So it's more like the squircle[1] shape used by Nokia in their Symbian and Meego phones.

I've collected few rounded square (squircles :)) codes using cairo (through luajit):

and two more here (but I forgot to put the links where I got the code from, and I don't recall being my original code):

  gfx:round_rect_a()
  gfx:round_rect_b()
  gfx:round_rect_c()
  gfx:round_rect_d()

The PaintCode team continue to impress... Great app! Really helped me to generate the drawing code for my custom, dynamic UIViews.

As a non-designer techie I'm always amazed when I see articles showing the subtle differences in the new iOS or OSX.

I usually don't consciously perceive the subtlety, so seeing these detailed articles helps me appreciate the effort that went into the design.

The new iOS icon shape seems to imitate ubuntu phone (http://www.ubuntu.com/phone/app-ecosystem).

What would i use this for?
