Looping for a specific time

Hello,
I'm using Excel 2007

I have the following code:

Sub Macro1()
With Selection.Interior
.Color = 255
End With
Application.Wait Now + TimeValue("00:00:01")
With Selection.Interior
.Color = 15773696
End With
Application.Wait Now + TimeValue("00:00:01")
With Selection.Interior
.Color = 255
End With
End Sub

Is there a way to have the color changing last for two minutes without having to copy it 120 times ?
Mike
