The form's BackColor and TransparencyKey properties are both set to red so the form is invisible. It is displayed maximized so its buttons can appear anywhere on the screen.
When the user clicks a button, the event handler creates a new button, positions it randomly, and adds the same event handler to it so it can create new buttons.

Private Sub btnClickMe_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles btnClickMe.Click
Dim btn As New Button
Dim rand As New Random
Dim x As Integer = rand.Next(0, Me.ClientSize.Width - _
btnClickMe.Width)
Dim y As Integer = rand.Next(0, Me.ClientSize.Height - _
btnClickMe.Height)
