An artwork may change into a variable installation in the course of its lifetime even though it started as 'frozen' installation or sculpture. To call it a variable installation depends on whether and when 'change' becomes a distinctive feature of the installation. The work may be seen as variable even though its specification for re-installation may be very specific. This very much depends on the artists' intentions and how they see their work evolving over time. (q) Terminology Workshop Inside Installations, 2006
