Custom Notifications

I want to make the code listed below and add a custom look to it.

function RAS.AddNotify( ply, message, kind, length )
    net.Start( "RAS.Notification" )
        net.WriteString( message )
        net.WriteInt( kind || NOTIFY_GENERIC )
        net.WriteInt( length || 2 )
    net.Send( ply )

Do that client side.

This might help:

So I can basically treat it as a menu
