Get-SPSite http://sharepoint2010 | % {

    $results = @()

    Get-SPFeature -Site $_ -Limit All | % {

    $feature = $_; 
        $featuresDefn = (Get-SPFarm).FeatureDefinitions[$_.ID]; 
        $cc = [System.Globalization.CultureInfo]::CurrentCulture;

        $obj = New-Object PSObject;
        $obj | Add-Member NoteProperty  Title  $($featuresDefn.GetTitle($cc));
        $obj | Add-Member NoteProperty  Hidden $($feature.Hidden);

        $results += $obj;
    }
