Matrix-Style Rain in PowerShell

01Command

$ while ($true) { $line = -join (1..80 | ForEach-Object { [char](Get-Random -Minimum 33 -Maximum 126) }); Write-Host $line -ForegroundColor Green; Start-Sleep -Milliseconds 60 }

02What it does

The loop builds a row of 80 random printable characters with Get-Random, writes it in green with Write-Host and pauses briefly with Start-Sleep. Change the range or the sleep to alter the density and speed. It is a fun demo of loops and .NET types.
