Changing Item Templates With Sitecore PowerShell

So I'm starting to explore the Sitecore PowerShell Console module from Adam Najmanowicz, and I think the community could benefit from a few more example scripts. I'm working on some enhancements to WeBlog that will allow you to more easily use different templates for each blog, which required me to change the template of a large number of entries. PowerShell made this easy once I figured it out:

$master = [Sitecore.Configuration.Factory]::GetDatabase("master");
$entryTemplate = $master.Templates["YouPhoria/Blog/Entry"];
cd master:\Content\Home\Blog\;
Get-ChildItem -recurse | ForEach-Object { if ($_.TemplateName -eq "BlogEntry") { $_.ChangeTemplate($entryTemplate) } };

And there you go.

Obligatory note: You could also do this using Revolver, a command prompt module from my WeBlog partner in crime Alistair Deneys.
