Startly Technologies Docktopus

Docktopus from Startly Technologies is a Mac OS X dock enhancement that gives you instant access to useful information and powerful new commands through your dock icons. Similar to the way Apple Mail uses a badge to display the number of unread messages from its dock icon, Docktopus allows you to overlay custom badges on your dock icons. An application's CPU and memory usage, a folder's contents, new messages waiting in a specific mail account and available disk space are just a few examples of the kinds of data Docktopus badges can display. All of this information is updated in real-time and because it is part of your Dock it is always available at a glance.
