According to Paul Dunn, the story of the hologram is briefly as follows:

The main shareholder at Third Dimension (Soloman Balas) aslo had a controlling share of a glass blowing company.  During a visit to them we discussed a method of making glass images of faces by making a sand imprint as a glass 'mould'.  The main glass blower had a friend also visiting (described as a local gay icon - but that is probably something that was more personal).  He had a fantastic face so I asked if they could use his face and allow me to make a hologram of the glass mould.  The intention was to make only two or three and display the glass sculpture in front of the hologram.  The results produced a stunning mix when lit  together.

We were asked for several copies and Soloman decided we should make a limited addition but obviously without the glass sculpture.
