Would you like to comment the following line:

Invoke-Expression $(".{" + $_lines[$_i] + "}| out-host")

Why not just writing:

Invoke-Expression $_lines[$_i]

It guess it has something to do with output formatting so you 'split' the output of each command by wrapping it in a separate scope so it gets its own formatting applied. But I'm not entirely sure what's going on here, especially the surrounding $() confuses me.

Oh, nice script by the way! ;-)

I've used the older versions in a number of demos and they've been really useful. I like the idea of being able to preview the commands - very useful. Thanks

For Maximilian Hanel - Check this post http://blogs.msdn.com/powershell/archive/2007/03/07/invoke-expression.aspx for an explanation of that line of code. You're correct in that it's related to the variable scope.

Hi, thanks for superb script. I am using it a lot and it's my favourite one :)

I only changed one small thing. Because it leaves title unchanged after the end of presentation (with time and command) I added few lines of code to the begin ($originalWinTitle = $Host.UI.RawUI.WindowTitle) and the end/q ($Host.UI.RawUI.WindowTitle = $originalWinTitle)
