You can see the transparency at the top opening of the bucket. Below an example of one of the buckets he created. However, you do not need to worry too much about this, since there are quite a few icon collections out there that can be used for our purpose (see “ Download Stack Overlay Icons” below).Ī Japanese designer, Yasushi Chida’s, has created some really nice looking buckets for this purpose – unfortunately his website at GeoCities/Yahoo is down and his Deviant Art page is empty. Now to make an overlay, we’ll need an icon, say one that is transparent mostly and kinda looks like a bucket.Īs for the file format for an icon, you could use the “ icns” file format if you want to create them yourself. Since the “stacked” icons are sorted alphabetically, you can see above, in figure 2, that the icon of “1Password” is on top (“1” comes before “A”). The idea behind dressing up a stack with a so called overlay, is based on the fact that icons of files and/or applications in that particular folder are “stacked” (placed on top of each other), and the fact that MacOS icons can be transparent.
