Just under a month ago, Minimax brought us Tagy, a cool little widget that would turn your app names into "tag clouds," where some would be bigger than others, based on your click frequency. Now, with Imgy, the developer has applied the same principle to app icons - have a look:

2012-07-01 11.51.59 2012-07-01 11.54.59 2012-07-01_16-44-34

After you select the apps / bookmarks / contacts you want, Imgy will create a homescreen widget (you can decide how large said widget will be) with icons for the selected content.
