An Out-Grid cmdlet implemented in what may possibly be the most complicated fashion ever ;-) David Barnhill has created a WPF app which you can instantiate from PowerShell by sending output to it... but the cmdlet actually creates a separate application object (a new process) and then communicates with it (using WCF) to send it the grid data.
