Hi all, I stumbled across a free app called Konfabulator recently. I guess it's been available for the Mac kids for quite a while. The program lets you set up various semi-transparent widgets on your desktop. Examples: System stats, local temp, stock ticker, ets. I like it a lot so far. It's unobtrusive and uses almost no resources. Of course, I run dual monitors and have all ny widgets on my secondary monitor. I don't know how much I would like the app if I had only one monitor.
