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.
