Just to prove a point regarding pixels that fits the pixelgrid vs pixels that don’t. The upper version shows icons just placed into the document, the lower version shows version hinted to fit the pixelgrid.. The difference is especially clear on straight lines f.ex. on the top of the calendar, and the lines inside the circle..
(Hope it is clear on the site as well, and that tumblr don’t scale the images.. :P) Probably a good idea to click on the image to view it in its right format.. :)
