I'd like something like this in Phobos, or if this is not possible, a cabal-install-like command away. I sometimes use Python PyGame or Processing.

Instead of:
image.putPixel(a, b, Color(a, b, ((a + b) % 16) * 16));
I suggest something simpler like:
image[a, b] = std.typecons.tuple(a, b, ((a + b) % 16) * 16);

Instead of:
image.display();
I suggest something like this, to swap the two image buffers:
image.flip();

Plus maybe some image.event(); reader with callbacks...
