The PowerShell Guy wrote an excellent script that produces a GUI for monitoring PowerShell scriptblocks:

Start-Monitor

I added

• automatic type-detection, so
  • columns are not sorted as text, but according to their type
  • numeric columns will be right-aligned
• option to run scriptblock from textbox
• option to save output to .csv
• some formatting
• standard module-documentation

Syntax Start-Monitor
   Start-Monitor [[-Interval] <Integer>] [[-Scriptblock] <scriptblock>]

Example
Start-Monitor

Description
Opens a blank form where you can enter a scriptblock.
Press Ctrl-R to execute the scriptblock.

Example
Start-Monitor.ps1 -Interval  30 -ScriptBlock {(gps | select PSResources,cpu -ExcludeProperty TotalProcessorTime)}
