There was a device that placed a pointer over the surface of the glass and an electronic circuit not unlike a metal detector would indicate when the outside pointer was aligned with the pointer behind the glass. I don't remember who developed it. It was either Tim Cranmer or Bob Gunderson. I don't know if they are still available.
